Deciphering the norms of AST AST in the blood of women, men, children

AST (aspartate aminotransferase) and ALT (alanine aminotransferase) are enzymes from the group of transaminases that are produced by the liver. To determine their level, a biochemical blood test or individual liver tests are performed, which reflect the functionality of the liver. Together with other indicators of biochemistry or separately, AST and ALT can indicate serious diseases of any organs and systems. Therefore, it is so important to know what the norm of these enzymes should be in women, men and children.

What do they mean

Transaminases are produced in the cells of various organs and transfer the amino acids alanine and aspartate from one biomolecule to another.

In the liver, the amount of enzymes reaches its maximum concentration. Also, ALT and AST are detected in the heart muscle, pancreas, kidneys and muscle tissue.

From the organs, only a small amount of enzymes enters the blood, but with various diseases their level and activity in the blood increases.

Norms

Normal liver function tests vary by sex and age.

• in women (from 18 years old) - 32;
• in men (from 18 years old) - 41;
• in newborns (the first 3-4 days) - 48;
• 4-6 months - 55;
• 3 years - 32;
• 6 years - 28;
• 11 years - 38.

Liver enzymes in pregnant women change slightly depending on the duration of pregnancy. In the first trimester, the indicators may differ from the norm by 5-10% in the direction of decrease or increase. This is not a pathology and does not indicate any serious illness.

Fluctuations in the level of ALT and AST are associated with the fact that for proper development the baby needs a large amount of vitamin B6, which is involved in the production of transaminases. When vitamin B6 is not enough, the body begins to take it from the muscles and liver cells, so enzymes are released into the blood. To compensate for the increased load on the body during pregnancy, women are prescribed a special complex of vitamins.

If, after the first trimester, the AST and ALT levels exceed the norm, the doctor may suggest preeclampsia and prescribe an additional study to clarify the clinical situation.

In the normal course of pregnancy in the second and third trimester, the level of enzymes should be from 29 to 31 units per liter. Such indications confirm that a woman's heart, liver and kidneys cope well with the increased load during pregnancy.

De Ritis coefficient

The normal de Ritis coefficient is 1.3. Its increase is characteristic of a heart attack, and its decrease is characteristic of liver disease.

Reasons for deviations

Alanine aminotransferase (ALT)

A slight increase in the activity of the ALT enzyme in the blood can occur due to the following factors:

• reception medicines- oral contraceptives, antibiotics, NSAIDs (Aspirin, Nurofen, Diclofenac, Paracetamol and others), cytostatics, sedatives (valerian, motherwort), echinacea, drugs, and so on;
• severe stress;
• reception alcoholic beverages and / or eating fatty / fried foods 7 days before the test;
• intensive growth in adolescence;
• serious physical activity (typical for athletes);
• various injuries.

In the case when the level of ALT is increased in the biochemical blood test, it is necessary to inform the doctor about all the medications taken in the last 2-3 weeks, especially about drugs and their analogues such as Carbamazepine (an antiepileptic drug), Cordarone (an antiarrhythmic drug), Fluconazole and Nizoral ( antifungal drugs), Ciprofloxacin (antibiotic), Atorvastatin and Simvastatin (cholesterol-lowering agents), Metformin (drug used to treat diabetes). After taking any of the indicated medications, the ALT level rises.

Increased ALT is the first sign of acute liver pathology. The growth of the enzyme is noted even in the incubation phase (1-2 weeks before the onset of symptoms) and precedes the maximum increase in blood bilirubin by 8-10 days.

The acute period of the disease is accompanied by an increase in the level of ALT by 5-10 times, while with implicit forms, liver tests may remain normal. If the elevated rate of the enzyme does not decrease for a long time or its growth is observed, extensive necrosis of the liver cells is likely.

Elevated ALT is characteristic of the following pathologies:

• obstructive jaundice due to cholelithiasis;
• acute hepatitis (with hepatitis C, the rate increases 10 times);

Reasons for a decrease in the amount of ALT:

• oncological pathologies of various origins;
• infections of the genitourinary system;
• disease pancreas;
• severe liver pathologies (necrotic atrophy of the organ);
• lack of vitamin B6.

Aspartate aminotransferase (AST)

The enzyme often increases with injuries and burns, heat stroke, mushroom poisoning.

High AST levels cause:

• hepatosis, hepatitis (drug, viral);
• liver cancer;
• cholestasis (stagnation of bile);
• mononucleosis;
• cirrhosis and developing necrosis of liver cells;
• autoimmune diseases that occur with muscle damage, for example, Duchenne myodystrophy;
• alcoholic toxic liver damage.

The AST indicator is of great importance in the diagnosis of myocardial infarction and the prognosis of the disease. The level of the enzyme increases to the maximum (exceeds the norm by 4-5 times) with the occurrence of necrosis of the heart. If the indicator does not decrease or increases in the next 5 days after a heart attack, the prognosis for the patient is very unfavorable. An increase in AST activity indicates widespread areas of necrosis.

Too low an AST value indicates extensive liver damage or a deficiency of vitamin B6, which is also involved in enzyme reactions.

When to take an analysis for ALT and AST

Basically, when a liver disease occurs in a patient, cytolysis is observed, in which the cells of the organ (hepatocytes) are destroyed.

The first signs of cytolysis:

• nausea and vomiting;
• bitter taste in the mouth;
• weight loss;
• severity with right side, pain in the right hypochondrium;
• jaundice skin;
• fatigue, weakness, lethargy;
• increase in body temperature.

Blood analysis

Biochemical blood test AST and ALT are prescribed for:

• admission medical preparations that can adversely affect the liver;
• abuse of alcoholic beverages;
• hereditary predisposition to the development of liver pathologies;
• after hepatitis (or suspicion of hepatitis);
• the presence of diabetes and excess body weight;
• suspicion of a violation of the liver, if the patient complains of nausea, vomiting, abdominal pain, lack of appetite, flatulence, discoloration of feces, yellowing of the whites of the eyes and skin;
• during therapy to determine the effectiveness of treatment.

The result of the analysis of ALT and AST is compared with other indicators in order to determine a more accurate form of pathology.

In addition to aspartate and alanine, they also determine:

• total protein in the blood. An increase in protein concentration indicates dehydration of the body, the development of chronic inflammatory processes.
• urea concentration.
• albumin concentration. An increase in the indicator indicates dehydration and liver failure.
• creatinine concentration. Increased values ​​indicate renal dysfunction, rupture Bladder, blocking the urethra.
• ALP (alkaline phosphatase). An increase in the value confirms hyperthyroidism, liver damage, diseases biliary tract, intestinal damage, Itsenko-Cushing's disease, generalized tissue damage (including neoplasms) and the presence of barbiturates in the body.
• GGT (gamma-glutamyl transferase). An increase in values ​​indicates liver necrosis and hepatocellular inflammatory processes.

Also, to make an accurate diagnosis, it is necessary to control the level of bilirubin, iron (to exclude hemochromatosis), cholesterol, prothrombin time, and to determine antibodies to hepatitis viruses (C, D, B).

Preparation for analysis

To reliably determine the level of enzymes before testing, it is necessary:

How to downgrade

To reduce the level of ALT and AST, the doctor prescribes drugs for the disease that caused the increase in enzyme levels in the blood. Treatment with hepatoprotectors will help protect the liver from exposure to various aggressive factors.

These medicines have a positive effect on the liver:

• protect cells from further damage, improve their nutrition;
• contribute to the restoration of cells;
• partially remove toxins from the body;
• speed up metabolism.

Hepatoprotectors differ in the mechanism of action:

• Essential phospholipids (Essentiale forte, Rezalut Pro, Phosphogliv, Phospholip, Livolin, Essliver forte), which are produced from soybeans. Effective hepatoprotectors plant origin that help lower liver enzymes. They are similar to the cells of the human liver and therefore are naturally embedded in diseased areas and help to restore them. Plant phospholipids have virtually no side effects. Rarely do they cause allergic reaction with individual intolerance or loosening of the stool.
• Vegetable flavonoids (Karsil, Silimar, Gepabene, Galstena, Legalon, Hepatofalk Planta). Natural compounds, natural antioxidants, the action of which is aimed at neutralizing free radicals. The preparations include medicinal plants: officinalis fumes, celandine, turmeric, milk thistle. The drugs have not only a hepatoprotective effect, but also eliminate the spasm of the gallbladder, improve the outflow of bile and its production. Therefore, they are prescribed for hepatitis, accompanied by cholecystitis and biliary dyskinesia.
• Amino acid derivatives (Heptor, Heptral, Hepasol A, Hepa-Merz, Hepasol-Neo, Hepasteril, Remaxol). They consist of protein components and other substances necessary for metabolism. They have a detoxifying effect, normalize metabolic processes and strengthen the body. They are prescribed for liver failure and severe intoxication. However, these drugs often cause such side effects like nausea, vomiting, diarrhea, abdominal discomfort.
• Ursodeoxycholic acid preparations (Ursodez, Ursodex, Urdox, Ursosan, Urso 100, Ursofalk, Choludexan and others). The composition of the drugs includes Himalayan bear bile, which improves the solubility and excretion of bile from the body, reduces damage and subsequent death of liver cells in various diseases, and has an immunomodulatory effect. Drugs that lower enzymes are prescribed for cholelithiasis, biliary cirrhosis, fatty hepatosis, alcohol intoxication.
• Vitamins (Vitrum, Supradin, Undevit and others). The drugs are effective for restoring liver functions, but only in combination with other drugs.

In addition to medicines, dietary supplements (Ovesol, Hepatrin, Milona-10, Dipana, LIV-52, Sibektan, Gepagard, Gepafor) and some homeopathic remedies (Hepel, Sirepar) have a hepatoprotective effect.

Diet

To reduce ALT and AST levels, it is also important to follow dietary nutrition.

From the diet should be completely excluded:

• alcoholic and carbonated drinks;
• smoked meats and pickled foods;
• flavoring seasonings;
• fatty meat and fish broths;
• fried foods;
• cereals and legumes;
• mushrooms;
• egg yolks;
• muffin;
• lard, fatty pork, lamb;
• coffee;
• chocolate.

• soups with light vegetable broth;
• low-fat dairy products;
• porridge (boil to a viscous state);
• natural juices without sugar;
• rosehip decoction;
• black tea with lemon;
• dietary meats (rabbit, beef, turkey, chicken);
• biscuit cookies;
• jelly;
• stale bread;
• fruits (apples, oranges);
• green leafy vegetables, broccoli, zucchini, carrots;
• nuts;
• cod liver, caviar.

You need to eat at least 5 times a day in small portions, you should also limit your daily salt intake to 8 grams per day and drink at least 2 liters of water.

How to boost

• Diagnose and treat the disease that caused the deviation.
• Take hepatoprotectors.
• Vitamin therapy is prescribed if the cause of the decrease in the level of AST and ALT was a deficiency of vitamin B6.
• Stick to a diet.

ALT and AST are the norm in women

The blood contains great amount various substances and elements. Most often we hear about erythrocytes, leukocytes, platelets. They talk about them in anatomy lessons. In fact, in the school course, something is mentioned about ALT and AST, as well as their norm in women. But, as a rule, this information safely passes by the ears and is forgotten.

The norm of ALT and AST in the blood of women

These substances belong to the group of enzymes. AST - aspartate aminotransferase - a blood component that promotes the movement of the amino acid aspartate from one biomolecule to another. ALT - alanine aminotranserase - is an enzyme that performs a similar function, transporting alanine. Both substances are produced intracellularly and enter the bloodstream in small quantities.

According to the norms, ALT in the blood of women should be no more than 30 - 32 units per liter. And the amount of AST in this case can vary from 20 to 40 units. If the indicators deviate from the normal value up or down, it means that changes are taking place in the body. And to make sure that they do not pose a danger, it is advisable to seek the advice of a specialist.

What do deviations of AST and ALT from the norm mean in a biochemical blood test?

The number of enzymes can also change slightly in the body of a healthy person. This can be influenced by:

• excessive physical activity;
• long-term use of potent drugs (antibiotics, barbiturates, narcotic drugs, sedatives, hormonal contraceptives);
• trauma;
• surgery carried out shortly before the examination.

Very often, ALT exceeds the norm in pregnant women. Such a phenomenon is not considered a deviation, and it does not signal a disease.

The main reason is hormonal changes. Usually, the level of enzymes returns to normal very quickly.

A deviation is considered critical if it differs by tens or even hundreds of times from the normal value. The following factors contribute to the excess of ALT and AST:

1. The level of alanine aminotransferase is markedly increased in hepatitis. Sometimes, thanks to the analysis for ALT and AST, type A disease is determined a week before the first signs of it appear.
2. Cirrhosis of the liver is a very secretive disease. For a long time, its symptoms may go unnoticed. And the fatigue characteristic of the disease is written off for another bad day. If the feeling of fatigue torments you with unenviable constancy, it is highly advisable to take a blood test. The alanine aminotransferase level will show if there is cause for concern.
3. Exceeding the norm of ALT and AST in the analysis may indicate a myocardial infarction. The disease develops against the background of circulatory disorders and is characterized by the death of heart tissue.
4. Mononucleosis can also be determined by the number of enzymes. This is an ailment of infectious origin, in which not only the composition of the blood changes, but also deformations of the liver and spleen are observed.
5. An increase in the amount of ALT and AST can also signal steatosis, a disease in which fat cells accumulate in large numbers in the liver.

In order for the tests to show a reliable picture, before passing them, you can not eat heavy food, alcohol. If you are taking any medications, be sure to tell your doctor about it.

ALT and AST below normal

With a sharp decrease in aspartate aminotransferase and alanine aminotransferase, specialists have to deal much less often. The problem is most often observed when:

AST and ALT: norms of transaminases in women and men before and after 50 years

A blood test for biochemistry allows you to judge the state of important organs and systems of the body. This research method shows the presence of diseases of the liver, kidneys, heart, vascular and endocrine systems in both men and women.

In the process of activity of this or that organ, various substances. Blood is present in all tissues of the body, so its composition allows you to accurately determine the presence and level of these substances.

What is AST and ALT

AST (AST, Asat, aspartate aminotransferase) is an enzyme that is found in the blood and is involved in the transfer of amino acids from one molecule to another. The reaction can occur if there is a coenzyme, in this case it is pyridoxine (vitamin B6). Most of all it is active in the liver, heart, kidneys, in the cells of muscle and nervous tissues.

ALT (ALT, Alat, alanine aminotransferase) is an enzyme that is also involved in the process of amino acid metabolism. In addition to the heart, liver, kidneys, muscle, nervous tissue, it is located in the pancreas.

Diagnosis of diseases

Blood biochemistry is widely used to clarify the diagnosis various diseases, it is assigned first. The correct interpretation of the biochemical blood test for the norms of AST and ALT in adult men and women helps to identify the presence of the disease at an early stage.

Biochemical analysis determines:

• Blood sugar - this indicator is the main indicator in the diagnosis of diabetes. The normal value of glucose is from 3.8 to 5.5 µmol/l;
• Bilirubin is common - it increases with hepatitis of various etiologies, cirrhosis of the liver, various anemias with an increase in the breakdown of erythrocytes, due to a violation of the outflow of bile during cholelithiasis. The norm is 3.4-17 µmol / l;
• AST, ALT - most of these enzymes are located in the liver, therefore, in a healthy state of the body, the concentration in the blood is small;
• Cholesterol is a blood lipid that enters the body with food, and is produced in small amounts by the liver. Norm ASAT and ALAT - 3.2-5.6 µmol / l;
• General protein - a decrease in protein in the blood occurs with certain diseases of the kidneys and liver. Norm - g / l;
• Albumin - the main protein of the body, increases with dehydration, indicators decrease with problems with the liver, intestines, kidneys. Norm - g / l;
• Urea, creatinine, uric acid– are final products protein metabolism, are completely excreted by the kidneys, so their increase indicates diseases of the genitourinary system;
• Potassium, sodium, chlorine - blood electrolytes, maintain water-salt balance;
• CRP (C-reactive protein) is a blood element that reacts faster than other indicators to inflammation and tissue damage. The higher the protein, the more acute inflammation. Norm - up to 5 mg / l;
• Iron - is found in the blood serum, is involved in the transport of oxygen. This indicator changes with diseases of the hematopoietic organs. The norm for women is 8.9-30.4 mmol / l, for men - 11.6-30.4 μmol / l.

The research indicators are quite reliable and are used in various fields of medicine: therapy, surgery, urology, cardiology, gynecology and others.

Preparation for blood collection

No special preparation is required for the analysis. However, in order for the result to be more reliable, some rules must be observed:

• The study is done on an empty stomach, the last meal no later than 12 hours;
• Eliminate alcohol for a week;
• Smoking - one hour before the procedure;
• On the eve, exclude strong physical exertion and stress.
• If the patient is taking hormones or non-steroidal anti-inflammatory drugs, inform the doctor.

The norm of transaminases in the blood

Indicators of transaminases in men

Men have higher enzymes than women. This is because men are more enduring and have more muscle mass.

The norm of ALT and AST in the blood in men:

Men are more likely to violate a healthy lifestyle, proper nutrition, with help bad habits They try to overcome stress and nervous shocks, as a result of which they are more likely to be at risk of various diseases.

The norm of ALT, AST in the blood of women and men after 50 years

As we age, body tissues can change. In this regard, the levels of enzymes in the blood increase. Risk factors for increasing aminotransferases in the body after 50 years are:

• Heredity;
• Transferred hepatitis or contact with the patient;
• Virus carriers various forms hepatitis;
• Alcohol consumption;

• Taking strong drugs;
• Diabetes;
• The presence of excess weight.

ASAT and ALAT values ​​during pregnancy

Enzyme indicators are measured in arbitrary units, in some clinics other units of measurement are used, when deciphering, one should take into account how the results are translated into other measurement systems.

The accuracy of a blood test for transamnasis norms in pregnant women depends on the equipment on which it is produced, therefore only a specialist can judge the significance of the result.

The norm of AST and ALT in women during pregnancy may differ from the usual level of enzymes in the blood and vary depending on the period. The reason is the altered hormonal background. In the first and last trimester, the concentration of enzymes in the blood increases. The excess can be several times. An increase in aminotransferases tenfold indicates the presence of a serious illness.

Table normal values enzymes in women in the 1st and 2nd half of pregnancy:

In the later stages, even a slight increase in transaminases indicates toxicosis (gestosis).

Enzyme levels in children

Norms of AST and ALT in the blood for children different ages different:

• In the first days of life - up to 48 units / l;
• Up to 6 months - 56 units / l;
• From 6 to 12 months - 54 units / l;
• From 1 year to 3 years - 33 units / l;
• From 3 to 6 years - 29 units / l;
• 6-12 years - no more than 39 units / l.

After 12 years, the values ​​of children's indicators begin to equate to adult values.

Causes of deviations from the norm

The greatest number of transaminases is found in the liver. If there are problems in this organ, aminotransferases (transaminases) help to identify damage and damage from the action of toxins or drugs even before signs of jaundice appear.

If the number of enzymes is greatly increased, ALT can be compared to AST:

• The normal value of the coefficient is 0.91-1.75;
• With an increase in the indicator more than 2, damage to the heart muscle is detected, myocardial infarction is possible;
• A decrease in the coefficient below 1 indicates liver disease, the lower the value, the greater the likelihood of an unfavorable outcome.

When men or women complain of weakness, fatigue, loss of appetite, nausea, vomiting, an analysis is not done to exclude hepatitis.

In addition to hepatitis of various forms, the rate increases due to diseases such as cirrhosis, oncology, and liver damage due to poisoning with toxic substances. You will learn more about elevated enzyme levels and treatment methods in a separate article.

The level of transaminases increases with:

• pancreatitis;
• Cardiovascular insufficiency;

• Burns on large areas of the body;
• tissue necrosis;
• shock states.

This laboratory method not only allows you to accurately establish the diagnosis, but also used during treatment, as it allows you to monitor the dynamics of the disease, improvement or deterioration of the patient's condition.

Blood for transaminase may also increase in the following cases:

• With factors that cause destruction of the liver (alcohol consumption, potent drugs);
• In contact with a patient with hepatitis;
• The presence of a hereditary predisposition;
• Diabetes;
• Excess weight.

A decrease in the concentration of enzymes in the blood is observed when the cause of the disease is eliminated within days. In case of diseases of the heart, liver, after the course of treatment and procedures, the blood test is repeated. At effective treatment transaminases should return to normal.

Sometimes, Duphalac, Heptral, Hefitol are used to reduce liver tests. But these remedies have contraindications, they must be taken into account, in addition, they do not relieve the cause of the disease. Especially, pregnant women should be treated with caution.

The norm of ALT and AST in the blood

The norm of ALT and AST in the blood of women has clear boundaries.

These indicators are determined during a biochemical blood test for the diagnosis of various diseases and mean different levels of enzymes in the blood plasma.

The norm of ALT and AST in women

In women, ALT values ​​are considered good if the concentration of these enzymes does not exceed 31 U / l.

The norm of ALT in women in the blood is a value ranging from 20 to 40 units.

The norm of AST in women in the blood of ME.

The presence of deviations of indicators up or down is evidence that certain changes are taking place in the body. If the indicators are increased by 2-5 times, then the increase is considered moderate. An increase of 6-10 times indicates an average increase in results.

If the indicators are 10 times or more higher than the norm, then this is a high increase. As a rule, to find out the causes and correct the results, an individual consultation with a specialist is required with the appointment of additional examinations.

The meaning of the terms ALT and AST

These are types of enzymes from the group of transferases, which are widely used in medical practice to detect the level of damage. internal organs.

Normally, only a small part of these enzymes enters the bloodstream. In the presence of certain pathologies, these enzymes are determined in the blood to a lesser or greater extent from the norm, which is determined by laboratory methods.

The level of ALT in the blood of a woman allows you to find out the presence and extent of liver damage. The level of AST allows you to assess, in addition to the state of the liver, the degree of damage to the heart muscle.

Causes of increased enzyme levels

Depending on the age of a woman, certain disorders in the tissues of the body may occur. In the future, this leads to the presence of overestimated ALT and AST.

Only a specialist can determine the cause of the increase, based on research.

Isolated increase in ALT

The main reason for the increase in ALT in women is the presence of liver diseases - hepatitis, cirrhosis of the liver, liver cancer. Also causes at any age are diseases of the pancreas, heart disease, diseases of the skeletal muscles and muscles, hypothyroidism. An important role in the list of causes is also occupied by injuries of the body, shock states and presence of burns.

Isolated increase in AST

The most common reason for detecting an elevated level of AST is the presence of heart pathologies in a woman, which increase with the age of older people.

When a myocardial infarction occurs, AST usually rises tenfold. Also, the increase in results is affected by the presence of such diseases as hepatitis, cirrhosis and liver cancer, obstruction of the biliary tract, acute pancreatitis.

Reasons for Simultaneously Increased Enzyme Levels

The simultaneous determination of the level of ALT and AST in the blood of a woman is considered a more informative and reliable result, showing the level of damage to internal organs.

In medical practice, there is the de Ritis coefficient, which indicates the ratio of ALT / AST. Normally, this coefficient is 1.3. With heart disease, the coefficient is detected above the norm, and with liver pathology - below.

After an attack of myocardial infarction, there is a simultaneous increase in ALT and AST, but AST increases by about 10 times, and ALT by about 2 times.

A simultaneous increase in these indicators can be in the absence of external signs- this indicates that hepatitis proceeds externally without symptoms, but there are active internal processes of destruction of the liver.

In some cases, a slight increase in results may be healthy women as a result of stress, physical overstrain and taking certain medications.

Signs that require mandatory testing:

• The presence of weakness.
• Feeling of prolonged loss of appetite.
• Presence of nausea and vomiting.
• Pain in the abdomen.
• Yellow skin tone and eyes.
• Darkening of the color of urine.
• The presence of a light stool.
• Feeling of itching.

Factors conducive to an increase in signs of ALT and AST after 40 and 50 years:

1. Previous hepatitis or contact with a patient with any form of hepatitis;
2. Alcohol abuse;
3. Hereditary predisposition to diseases of the liver and heart;
4. Taking medications that can adversely affect the condition of the liver;
5. Presence of diabetes or other chronic diseases;
6. The presence of excess weight.

Research as a criterion for diagnosing diseases

A biochemical blood test, including these indicators, is prescribed if the following pathologies are suspected:

• Any diseases of the heart and blood vessels.
• Any pathology of the liver.
• Renal failure.
• various infections.
• Any autoimmune disease.
• Cholelithiasis.
• Pancreatitis - chronic and acute.
• Pathology of the endocrine system.
• Skin diseases accompanied by itching.
• Malignant tumors of any localization.
• Body poisoning.
• Encephalopathy of unknown origin.

In case of unfavorable results of ALT and AST, a pregnant woman is prescribed an additional series of examinations.

Treatment of diseases depending on the results of the analysis

The results of ALT and AST tests are necessary for treatment and health monitoring during and after the prescribed therapy.

ALT and AST indicators are used in preparation for any kind of surgical interventions in order to identify contraindications and possible complications.

Also of no small importance is the long-term use of drugs that affect the internal organs - antibiotics. a wide range actions, hormonal drugs, chemotherapy drugs.

Rules for passing the analysis

The analysis is carried out in any public clinic and private laboratory.

In order to obtain reliable results of tests for ALT and AST, a woman must adhere to the following rules:

• Do not eat for 8-12 hours before the study.
• Eliminate any physical activity and overexertion 30 minutes before the study.
• Eliminate psychological stress 30 minutes before the study.
• Stop smoking 30 minutes before the test.
• Refrain from drinking alcohol and fried foods a day before the study.
• Warn the specialist about the medications you are taking.

Folk remedies to normalize the level of enzymes in the blood

The indicators of ALT and AST in the body of each woman indicate the presence of her actual health. The norm is ALT - 32 units per liter, AST - from 20 to 40 units per liter, any deviation from the norm in one direction or another is considered a reason for additional examinations in order to identify the presence of diseases of the internal organs. I would also like to note that for women during the period of bearing a child, there are their own ALT and AST values.

Most women, before embarking on a rational traditional treatment, usually used folk remedies. It turns out that this is not only possible, but even supported by the attending physicians.

There are a great many recipes for reducing overestimated indicators, the most effective ones are listed below.

1. Milk thistle seed drink. Crushed seeds in the amount of 1 teaspoon pour 200 milliliters of boiling water. The vessel with the contents is tightly sealed and allowed to infuse for 20 minutes at room temperature. Then the infusion is filtered and taken orally 2 times a day, 1 glass half an hour before the main meal. It should be remembered that you can not drink the decoction in one gulp. Course treatment lasts 21 calendar days.
2. Herbal tea. To prepare it, you need to have St. John's wort, immortelle and celandine in the ratio 2:2:1 (tablespoons). Grind the grass, transfer it to a vessel that can be tightly sealed, pour a liter of boiling water and put it in dark place for 12 hours for infusion. After the time has elapsed, the infusion is boiled for 10 minutes, and then cooled at room temperature. Next, the broth should be filtered and taken orally 100 milliliters after meals 4 times a day. Course treatment lasts 2 weeks.
3. Dandelion root extract. Pour 200 grams of crushed root with 100 milliliters of vodka and add 30 milliliters of glycerin. Seal the vessel with the contents tightly and place in a dark, cool place for 24 hours. Then strain the infusion and take orally 2 tablespoons before the main meal 3 times a day. The duration of the course of treatment should be discussed with the doctor.
4. Collect hairs from ripe corn cobs. Dry them in vivo and grind. Next, prepare a drink from 1 teaspoon of chopped dry hairs and 200 milliliters of boiling water. It should be kept after pouring for ¼ hour, then strain and take orally 1 glass 2 times a day. Course treatment can last up to six months.

The general opinion of those who took these funds

Before starting treatment folk methods, many patients are interested in the reviews of those people who have already tried these recipes on themselves.

So, the above are the most effective of folk recipes to reduce AST and ALT. Therefore, there are a great many reviews about them, but putting them all together, we get the following picture:

• after taking milk thistle, the indicators were significantly reduced by the second biochemical blood test;
• corn hairs have the necessary effect, but it is not possible to sharply reduce the performance;
• dandelion root infusion is very effective but should not be taken while driving vehicle because alcohol is present in the composition;
• herbal tea helps to cope with the situation and after two weeks of daily intake you feel much better, especially since it allows you to strengthen your immune system, but the main inconvenience is its 4-fold use, you have to take it with you in a thermos to work so as not to miss a dose .

Each patient should remember that his body is individual and even with a million positive feedback treatment may not work. For example, when taking milk thistle in the first two days, there may be sensations of pain in the liver area - this is the norm, but if this feeling does not leave the person during subsequent treatment, then this fact indicates individual intolerance.

Therefore, starting any treatment, you should strictly monitor the reaction of your body and if you have any questions, you should always consult with your doctor. Since the patient needs to get rid of the disease, and not aggravate the situation.

Possible consequences of elevated enzyme levels if left untreated

Sometimes, it seems to women that they can start treating the disease later, because nothing supernatural will happen in one or two days, and today there is absolutely no time to go to the doctor and prescribe drugs. Of course, if the indicators are not very high, then one day will not play a role, but when the start of rehabilitation is postponed for a month or more, then there is nothing good to expect. The thing is that while a person delays his visit to the doctor, the disease does not doze, but conquers a new large territory.

And before you give up on elevated ALT and AST, you need to know very well what this can turn out to be if left untreated:

• cirrhosis of the liver;
• hepatitis;
• myocardial infarction;
• stagnation of bile and, as a result, intoxication of the body;
• liver oncology;
• hepatosis.

Each of the above diseases, in the absence of measures taken to eliminate it, can provoke a fatal outcome. But in cases of determining its development on early stages you can get rid of the disease without deplorable consequences.

Prevention of the occurrence of an increase in women

Any disease is best prevented than long-term treatment, which is why there is a concept of preventive measures.

In order for the indicators of ALT and AST in the blood of women not to rise to the heights, you should first of all reconsider your entire algorithm of life.

1. Give up bad habits. Alcohol and tobacco do not benefit anyone, but female body more addictive.
2. Follow nutrition. Avoid fried, salty, spicy and smoked foods. Enrich your diet with raw vegetables and fruits. Get into the habit of having breakfast in the morning not with coffee sandwiches, but with porridge with tea or jelly.
3. Avoid unnecessary stress. In cases where, nevertheless, fate presented an unpleasant surprise, then perhaps you should drink a course sedatives than to drive yourself into a trap.
4. Take as a basic rule - to be in the fresh air for at least 2 hours a day. If it doesn't work during the daytime, then it should be evening walks.
5. Make a daily routine and stick to it. Only the correct alternation of work and rest of the body will allow a woman to save it.
6. Have a permanent sexual partner. Promiscuity in intimate relationships can be a provocateur of the development of various kinds of diseases and, as a result, an increase in ALT and AST.
7. Periodically donate blood for analysis and monitor your ALT and AST levels (at least once every six months), especially after reaching the age of 35.

All these simple rules, in case of their implementation, will allow the woman to maintain her own health, which means that the ALT and AST indicators will remain within acceptable values.

The liver is the most important organ, on the work of which the health of a person and the beauty of his skin depend. After all, it is he who takes an active part in digestion, as well as in the neutralization of allergens, poisons and toxins that have entered the body. Alanine aminotransferase (ALT) plays a key role in liver function. This endogenous enzyme, located in the cell of the organ, is involved in the exchange of amino acids. It also performs an important mission - cleanses the gland of toxins.

A small amount of organic matter can also be found in the blood. However, if the cells are destroyed, ALT is released and its level in the blood increases. In this case, they talk about the destruction of the liver. In order to find out if everything is in order with this organ, doctors prescribe a biochemical blood test that detects the level of ALT, the rate of which you will find out in an article from the Internet edition of the site.

ALT: the norm in human blood

Biochemical analysis of blood has been used in medical practice for a long time. After all, it is he who helps to identify the pathology of any organ, including the liver. To examine this digestive gland, doctors prescribe an ALT test. It allows you to accurately determine the level of enzymes in the blood and the presence of possible diseases. In order for the results to be as reliable as possible, it is necessary to prepare a little for such an examination:
. 12 hours before the test, do not eat;
. the day before blood donation, do not take aspirin, valerian tablets, paracetamol and contraceptives;
. a week before the examination, do not drink alcohol;
. before analysis, avoid smoking, unrest, as well as moral and physical stress.

Blood for examination is usually taken from a vein. And the results of the analysis are ready on the second day after delivery. Correctly interpreted analysis shows the correct clinical picture. Only a doctor can find out if everything is in order with the liver, based on the results of the analysis. However, each person can find out what ALT norm is. So, in medical reference books it is written that the normal amount of enzymes in the blood of women is 31 U / l, and in men - 41 U / l. In children, the rate usually does not exceed 50 U / l.

Very often, the results of ALT are compared with the results of AST, an enzyme that is also synthesized inside the cell. In medicine, this phenomenon is known as the de Ritis coefficient.

The optimal value of the de Ritis coefficient is from 0.91 to 1.75. A score greater than 2 indicates damage to the heart muscle. And if the coefficient does not exceed 1, it means that there is a liver disease. And the lower the score, the more serious the problem.

The analysis is usually prescribed as a diagnosis in cases where there are factors in a person’s life that destroy liver cells: frequent consumption of alcohol and fatty foods, smoking, as well as the abuse of paracetamol, contraceptives and other medications.

Also, doctors recommend being examined for diabetes and overweight. It is necessary to check the level of ALT even if there was contact with a patient with hepatitis. Often, a biochemical blood test is prescribed for pain under the right rib, nausea, and the presence of yellow skin.

When is ALT elevated?

The deviation of the level of organic matter from the norm indicates that the body has a disease, often associated with the liver. So, an increase in the amount of alanine aminotransferase tenfold indicates the presence of one of several liver diseases:
. Hepatitis. In chronic disease, the level of ALT is slightly elevated, and in viral hepatitis, the amount of alanine aminotransferase is significantly exceeded. If you have hepatitis A, timely analysis allows you to identify the disease at an early stage.
. Cancer - such a disease is very often a consequence of hepatitis. Thanks to the analysis for ALT, this insidious disease can be detected quickly enough, and treatment can be started on time.
. cirrhosis. The danger of such a disease is that it does not manifest itself for a long time. A person feels only slight fatigue and pain in the liver. You can find out about the presence of an ailment by exceeding the enzyme by 5 times.

Far from always, an increase in the level of the enzyme indicates a disease. ALT, the rate of which is slightly increased, very often indicates pregnancy. The fact is that in the last trimester, women often experience preeclampsia, which is accompanied by general weakness, dizziness and increased pressure. And this, in turn, leads to a deviation of the enzyme level from the norm.

There is also a decrease in the amount of organic matter. This happens when the body lacks folic acid and vitamins. And a significant drop in the level of enzymes in cirrhosis of the liver indicates the absence of healthy cells.

Common Symptoms of Abnormal ALT

You can find out that the amount of enzymes in the blood is increased or decreased even before a biochemical examination. Often this pathology manifests itself as follows:
. pain under the right lower rib;
. nausea;
. vomit;
. weakness;
. yellowing of the skin and eyes;
. hyperthermia;
. spider veins on the body;
. an increase in the abdomen;
. varicose veins veins of the anterior abdominal wall.

If one or more symptoms are found, it is imperative to consult a doctor. After all, these manifestations can indicate a serious disease, which, if not treated in time, can result in a complication and even death.

How to normalize the level of ALT in the blood

If, after passing the analysis, a deviation from the norm was found, the doctor usually prescribes an additional examination, which allows you to find out the true cause of the pathology. Already after it is known what exactly led to the deviation from the norm, the specialist prescribes a course of treatment, after which the ALT level should return to normal.

Also, to reduce the level of enzymes in the blood, the doctor may prescribe a special drug. The medication should be taken only under the strict supervision of the attending physician. And it is very important to read the instructions for contraindications before using the medicine.

Keep in mind that such drugs only alleviate the condition, but do not eliminate the problem. Therefore, first of all, it is still necessary to cure the disease itself from an experienced doctor. Then there will be no trace of the problem, the liver will recover, and the skin will regain a healthy color.

If they enter the bloodstream, this indicates the presence of some kind of organ malfunction due to cell destruction.

When ALT levels are elevated, it most often indicates the development of a certain disease affecting the liver. Deciphering the blood test can show in more detail which organ is damaged, the level of ALT or AST will be significantly increased in it.

What is ALT in a blood test?

Why is ALT elevated in a blood test, and what does it mean? Alanine aminotransferase (ALT) is an endogenous enzyme belonging to the group of transferases, a subgroup of transaminases, or aminotransferases. Determination of its level in the blood is widely used in medical practice to detect pathologies of the liver and some other organs. A blood test for ALT is almost always carried out in conjunction with determining the level of AST.

Evaluation of these two laboratory parameters allows the doctor to suggest localization pathological process and determine the likely severity of the disease. For the assessment, the Ritis coefficient (AST / ALT ratio) is used, which is normally 1.33. In acute viral hepatitis, this coefficient decreases, while in myocardial infarction and alcoholic liver damage it increases.

Where is ALT found?

The main function of alanine aminotransferase is associated with the exchange of amino acids. This substance acts as a catalyst in the transfer of certain molecules. When energy metabolism is disturbed, the permeability of cell membranes increases, which leads to cell destruction and the release of the enzyme into the blood serum.

Norm

The norms in which alanine aminotransferase in the blood should fit are as follows:

• children under 1 year old: 13 - 45 U / l;
• men up to 1 - 60 years old: 10 - 40 U / l;
• women 1 - 60 years old: 7 - 35 U / l.

In analytical studies for this enzyme, high accuracy is required, and it is directly related to the intake of certain drugs that can distort the analytical picture. Therefore, before checking the level of ALT, you should consult with your doctor, who will either temporarily stop taking medications or take into account deviations in the results of the analysis associated with drug therapy.

Elevated ALT in the blood: causes

In simple terms, alanine aminotransferase is an enzyme that, in addition to the liver, where its concentration is especially high, is located literally in all parenchymal organs, occupying mainly the cytoplasm of tissue cells. AlAT is not in vain considered a kind of marker of liver pathology and is regarded as a reliable sign of damage to its parenchyma, because the activity of the enzyme in the blood plasma is directly dependent on the degree of involvement of the tissue of this important organ in the pathological process.

Given this high sensitivity of ALT, it can be expected that alanine aminotransferase will be elevated in cases of the slightest hepatic parenchymal distress.

So, an increase in ALT occurs in the following cases:

1. Hepatitis. This inflammatory disease liver can be presented in several forms. For chronic or viral hepatitis, the excess of the level of alanine aminotransferase in the blood is insignificant.
2. Occasionally, an increase in ALT can be observed in cases of obstructive jaundice, but high values ​​​​of this indicator are extremely rare.
3. Cirrhosis. This disease is dangerous because for a long time it may not have pronounced symptoms. Patients quickly get tired, feel tired.
4. Liver cancer. This malignant tumor often occurs in patients with hepatitis. Analysis for ALT in this case is necessary both for diagnosing the disease and for making a decision on the surgical decision.
5. Non-alcoholic fatty liver disease (steatosis): ALT levels rise slightly - 2-3 times. With the transition of the disease to the phase of steatohepatitis, there is a pronounced increase in ALT, a high level of total and direct bilirubin, as well as indicators of inflammatory activity of the blood.
6. Pancreatitis. The presence of this disease is also indicated by the level of ALT. Its increased amount indicates an exacerbation of pancreatitis.
7. Myocarditis. It manifests itself in lesions of the heart muscle. Its main symptoms are shortness of breath, rapid fatigue of the patient and an increased content of ALT in the blood.
8. Myocardial infarction. This disease is a consequence of impaired blood flow, resulting in necrosis of the tissues of the heart muscle.
9. Tests can show an increase in ALT levels with alcoholism and immediately after drinking alcoholic beverages.

With an increase in the level of ALT by 5 times, myocardial infarction can be assumed, if it reaches times, we can talk about the deterioration of the patient's condition after an attack. The value of the de Ritis coefficient in this case also changes upwards.

Acute hepatitis provokes an increase in the content of the enzyme in the blood at a time, muscular dystrophy and dermatomyasitis - in 8. About gangrene, acute pancreatitis says the excess of the upper limit of the indicator by 3-5 times.

Reasons for increasing ALT are not associated with diseases

Other reasons can also increase the level of ALT in the blood, for example, certain drugs, such as estrogens, oral contraceptives, cholestatics, steroids, iron salts, a nicotinic acid, sulfonamides, methyldopa, azithromycin, aminoglycosides, cephalosporins, fluoroquinolones, clofibrate, clindamycin.

In some cases, physiological reasons become the cause of an increase in the level of alanine aminotransferase:

Taking dietary supplements containing components that adversely affect liver cells;

Drinking alcoholic beverages a week before the deadline for taking a blood test for ALT;

Emotional stress that can lead to malfunctions of the nervous system, and as a result, the body's reaction to it;

Improper nutrition - in particular, the use of foods with harmful food additives: convenience foods, "fast food", sugary carbonated drinks, etc. - in this case, when adjusting the diet, the ALT indicator returns to normal.

Of course, mainly the level of the enzyme increases due to other health problems, but it is for the above reasons that the indicator can be increased, but not significantly.

What to do when ALT in the blood is elevated?

If the ALT blood test is elevated, then a more complete examination is necessary to identify the cause of this change. And the sooner this is done, the better the outcome will be.

Most often, hepatoprotectors are prescribed to reduce ALT levels:

These drugs have numerous effects. First of all, they protect liver cells from further damage, and also restore already damaged, but not yet dead cells.

Causes when ALT is elevated. What does this mean?

What is ALT?

Alanine aminotransferase (also ALT, ALT) is a protein enzyme that is responsible for the transport of certain molecules and the acceleration of biochemical processes involving amino acids.

ALTs are found mostly in the cells of organ tissues. In healthy people, ALT in the blood cannot be elevated, since if ALT is released into the blood, a serious disease is likely to occur in some part of the body.

Most of all, ALT is found in the liver, and it can also be found in the kidneys, heart muscle, nerve connections, and lungs. Damage to these organs and tissues can cause an increase in ALT in the blood.

Optimal value in the body

This parameter is measured in units per liter of blood. ALT is age dependent in childhood, and in adults it is gender dependent.

Children under one year old: no more than 55 units / l

Children 1-3 years old: no more than 34 units / l

Children 3-6 years old: no more than 30 units / l

Children 6-12 years old: no more than 39 units / l

Men: no more than 45 units / l

Women: no more than 35 units / l

The norm in this case is not a strict and only possible value, but an approximate evaluation criterion. In some laboratories, the devices may have a different degree of sensitivity, which means that the results of the analysis should be discussed with the attending physician of this medical institution.

Alanine aminotransferase is elevated, what does this mean?

According to the degree of difference between the actual result of the analysis and the value taken as the norm, they distinguish:

• Slight increase (by%);
• Moderate increase (up to 1000%, that is, 10 times more);
• Pronounced (more than 10 times the norm).

The second and third stages most likely indicate that elevated ALT in the blood is a consequence of the disease, and the third case occurs in those patients who have already begun serious destruction of the organ.

In addition to the diseases that we will discuss below, elevated ALT may be associated with the following distorting factors:

• muscle injury;
• burns;
• Intramuscular injections made the day before;
• Large weight (body mass index greater than 30);
• Taking medications (estrogens, antibiotics, cholestatics, heparin, oral contraceptives, anti-epileptic drugs, warfarin, echinacea, valerian, etc.);
• Mononucleosis;
• Pregnancy (third semester), provided that ALT is slightly elevated;
• Chemotherapy;
• drug use;
• lead intoxication;
• laboratory inaccuracies.

In order to get a reliable result, it is necessary to donate blood on an empty stomach, 12 hours after the last meal. Refrain from alcohol a week before going to the clinic, and an hour before donating blood - from smoking. Try not to worry and not to be physically overloaded. If you doubt the reliability of a blood test, take it to another laboratory.

To determine if normal or elevated ALT in the blood, more often blood is taken from a vein, but in some cases from capillaries.

Causes and diseases when ALT is elevated in the blood

Since the enzyme under study can linger in various organs, it may indicate problems with their health. Consider what it means "ALT increased" in each case.

The largest amount of ALT, as already mentioned, is located here, it is not surprising that this analysis is recognized in time to notice and cure liver diseases.

The accumulation of fat in the liver cells affects the fact that ALT is increased by 2 times. But if the disease condition worsens to steatohepatitis, ALT will increase much more, and bilirubin levels will also increase.

If the ALT is elevated in the blood test, and the symptoms of the disease have not yet appeared, it may be from hepatitis A. Usually, the symptoms are delayed, and due to the timely donation of blood for analysis, the recovery process can be accelerated.

With hepatitis B and C, ALT increases even 100 times, since the toxic effect of the virus common in the liver is especially great on its cells.

Chronic hepatitis causes an increase in ALT during an exacerbation, but the increase usually occurs no more than 3-4 times.

Other symptoms of hepatitis include pain and discomfort in the right side, under the ribs, a bitter taste in the mouth, yellowing of the skin, mucous membranes, whites of the eyes, and impaired stool.

A very high ALT in the blood may not be observed in cirrhosis. ALT will rise, but 1-5 times the norm. This is due to the replacement of liver cells with connective tissue.

Usually malignant tumors in the liver appear in people with hepatitis. The level, how much alanine aminotransferase is increased, helps to decide on further treatment cancer surgically. For example, if ALT is very high, the operation has a great risk of complications.

A disease more common among women than among men. To clarify its presence or absence, the doctor may prescribe a biopsy.

Diseases of the heart, or rather the heart muscle, are primarily indicated by another analysis - AST, but along with it, ALT is also used for diagnosis.

The death of a part of the heart muscle, as a result of which a certain amount of AST and ALT enters the bloodstream. If the analysis of AST is greatly increased and alanine transaminase is increased by 5 times, the reasons should be sought in the possibility of myocardial infarction.

Other symptoms: sharp pain in the region of the heart, radiating to the left upper side of the body, the pain can last half an hour or more, the patient has shortness of breath, dizziness, panic fear of death, weakness.

As with other diseases of the heart muscle, myocarditis cannot be established solely on the basis that ALT is elevated. The reasons for this may be varied. Often, to clarify the diagnosis, an analysis of AST is also considered and the de Ritis coefficient is calculated equal to ALT / AST.

Symptoms include shortness of breath, weakness, fatigue of the patient.

Heart failure, rheumatic heart disease, recent heart surgery can also cause an increase in ALT in the blood.

The disease can occur in acute or chronic form. An increase in ALT indicates the stage of exacerbation. It is advisable for people with pancreatitis to donate blood regularly for ALT analysis.

AlAT elevated in a blood test can be an alarming bell for any serious and even destructive diseases, or it can be a common mistake or a normal reaction of the body. The prompt diagnosis and possible treatment depends on your further examination.

Elevated levels of ALT in the blood - the main causes

ALT, alanine aminotransferase. It is a specific enzyme involved in the production and breakdown of proteins. Synthesized by cells of various organs: liver, spleen, kidneys, lungs, heart muscles. Normally, a small amount enters the bloodstream. Blood ALT testing is a common diagnostic test.

Diagnosis based on ALT analysis

The detection of the level of alanine aminotransferase is carried out as part of a general biochemical blood test. Complaints for which a blood test for ALT is prescribed are:

• Increased fatigue;
• Decreased appetite;
• The appearance of weakness in the body;
• Pain on the right side of the abdomen;
• change in the color of urine;
• Yellowness of the skin;
• Pain in the region of the heart;
• Inclination to nausea.

Possible diseases with elevated ALT

It is mandatory to identify the level of aminotransferase in patients suffering from obesity, diabetes, liver disease.

Important! Blood donation is done in the morning on an empty stomach. It is not recommended to consume alcohol and fatty foods the day before the analysis.

It is also worth refraining from taking strong medications. The results of the study may be affected psycho emotional condition human and physical stress.

Exceeding the threshold of normal

In medical research, the upper limit of normal ALT is important. The limit for adult men is 45 units / l, for women 34 units / l. An increase in ALT in a blood test indicates an inflammatory process in the body. The following are the diseases that cause such a pathology.

1. Pancreatitis. Severe damage to the pancreas. It occurs due to the appearance of a tumor that blocks the enzyme ducts. As a result, the accumulated digestive enzymes begin to digest the pancreas itself. Possible lethal outcome;
2. Hepatitis. Liver disease. It is characterized by inflammation of the tissues of the body. It is divided into several types. Hepatitis C is considered the most dangerous. The latter often turns into chronic form and can cause cirrhosis of the liver. Common causes of hepatitis are: toxic damage to liver cells (for example, alcohol), viral infection;
3. Myocardial infarction. The most severe heart disease. It is characterized by the death of some parts of the heart muscle, due to a critical decrease in blood circulation. There are many reasons for pathology. The main ones: smoking, hypertension, obesity, diabetes, sedentary lifestyle.

There are reasons for exceeding the ALT norm in a blood test that are not associated with the listed diseases:

• Chemotherapy;
• Injuries accompanied by damage to the muscles of the body;
• Taking strong drugs;
• Physical and emotional overstrain;
• Eating fatty fried foods
• Taking drugs.

Important! The main recommendations aimed at reducing the likelihood of these diseases will be: proper nutrition, refraining from using drugs (including alcohol, nicotine), moderate physical activity, and reducing stressful situations in life.

De Rittis ratio

One of the most important research methods is considered to be the comparison of the level of ALT with the level of AST - aspartate aminotransferase. The latter is also an endogenous enzyme involved in the synthesis of amino acids. Aminotransferases have similar threshold levels in the blood. The diagnosis of a particular pathology depends on the balance of ALT and AST. The AST/ALT ratio is characterized by the de Rittis coefficient.

Important! The normal value of the de Rittis coefficient is 1.33-1.75 units / l.

A decrease in the rate below 1 unit / l will mean viral liver damage. Increasing the coefficient to 2 units/l and above, provided high content albumin, indicates myocardial infarction.

Normal levels of ALT / AST in the body:

• Alalnin aminotransferase: men - up to 45 U / l, women - up to 34 U / l;
• Aspartate aminotransferase: men - up to 41 units / l, women - up to 31 units / l.

Independent interpretation of analyzes

Often, patients, having read medical information, try to independently decipher a blood test for ALT levels. After receiving the results in the laboratory, some people, seeing the deviation of indicators from normal values, self-diagnose serious diseases in themselves.

Doctors know that exceeding ALT thresholds is not always a sign of pathology. Results from different laboratories may differ from each other. It depends on the equipment, on the research methods, on the materials used in the analysis. Also, other factors can influence the results, whether it is the patient’s wrong lifestyle, medication, emotional state, and others.

Only a doctor can correctly decipher the results of the research. He also prescribes medication.

To date, physicians do not use ALT analysis as a means of accurate diagnosis. An excess of ALT in a blood test indicates only the possibility of a disease. To make a final diagnosis, additional studies are used, specialists of a narrow profile are involved: urologists, cardiologists and others.

Normalization of ALT levels with folk remedies

After the examination, a patient with a high ALT level is prescribed medication. But for prevention, the doctor may recommend herbal medicine. The following are examples of the use of folk remedies to reduce the level of alanine aminotransferase.

• Milk thistle decoction. To prepare a teaspoon of chopped herbs, pour a glass of boiling water, wrap and let it brew for 20 minutes. Then filter the infusion. Take a decoction in small sips, half an hour before meals twice a day, for three weeks;
• Herbal collection. Immortelle, St. John's wort and celandine are mixed. The proportion of herbs is accordingly. The collection is poured with 1 liter of hot water, wrapped and infused for 12 hours. Then you need to strain the infusion. Take half a cup 4 times a day for two weeks;
• Dandelion infusion. For cooking, take 200 g of crushed dandelion flowers. Pour 100 ml of vodka. The remedy is insisted during the day. Take 2 tablespoons three times a day for three weeks;
• A decoction of corn stigmas. To prepare the product, dried crushed stigmas are taken. Pour 200 ml of boiling water and leave for minutes. Take the infusion twice a day in a glass. The course of treatment can be six months.

Important! Folk remedies are not a cure! They are used for the prevention of diseases and general strengthening of the body.

State of the art modern medicine allows you to accurately diagnose most known diseases. One of the generally accepted research methods is a biochemical blood test. It contains many indicators, one of which is the level of alanine aminotransferase.

Exceeding the normal level of ALT indicates the possibility of developing serious diseases in the body. But only a doctor can accurately determine the disease. We strongly recommend that you do not engage in self-diagnosis, and even more so self-treatment. At the appearances anxiety symptoms contact the clinic immediately. They will conduct all the necessary examinations and help you cope with the problem.

How to get rid of varicose veins

The World Health Organization has officially declared varicose veins one of the most dangerous mass diseases of our time. According to statistics over the past 20 years - 57% of patients with varicose veins die in the first 7 years after the disease, of which 29% - in the first 3.5 years. The causes of death vary - from thrombophlebitis to trophic ulcers and the cancerous tumors they cause.

The head of the Research Institute of Phlebology and Academician of the Russian Academy of Medical Sciences spoke about how to save your life if you were diagnosed with varicose veins. See full interview here.

AST and ALT: norms of transaminases in women and men before and after 50 years

A blood test for biochemistry allows you to judge the state of important organs and systems of the body. This research method shows the presence of diseases of the liver, kidneys, heart, vascular and endocrine systems in both men and women.

In the course of activity of this or that organ various substances are formed. Blood is present in all tissues of the body, so its composition allows you to accurately determine the presence and level of these substances.

What is AST and ALT

AST (AST, Asat, aspartate aminotransferase) is an enzyme that is found in the blood and is involved in the transfer of amino acids from one molecule to another. The reaction can occur if there is a coenzyme, in this case it is pyridoxine (vitamin B6). Most of all it is active in the liver, heart, kidneys, in the cells of muscle and nervous tissues.

ALT (ALT, Alat, alanine aminotransferase) is an enzyme that is also involved in the process of amino acid metabolism. In addition to the heart, liver, kidneys, muscle, nervous tissue, it is located in the pancreas.

Diagnosis of diseases

Blood biochemistry is widely used to clarify the diagnosis of various diseases, it is prescribed in the first place. The correct interpretation of the biochemical blood test for the norms of AST and ALT in adult men and women helps to identify the presence of the disease at an early stage.

Biochemical analysis determines:

• Blood sugar - this indicator is the main indicator in the diagnosis of diabetes. The normal value of glucose is from 3.8 to 5.5 µmol/l;
• Bilirubin is common - it increases with hepatitis of various etiologies, cirrhosis of the liver, various anemias with an increase in the breakdown of erythrocytes, due to a violation of the outflow of bile during cholelithiasis. The norm is 3.4-17 µmol / l;
• AST, ALT - most of these enzymes are located in the liver, therefore, in a healthy state of the body, the concentration in the blood is small;
• Cholesterol is a blood lipid that enters the body with food, and is produced in small amounts by the liver. Norm ASAT and ALAT - 3.2-5.6 µmol / l;
• General protein - a decrease in protein in the blood occurs with certain diseases of the kidneys and liver. Norm - g / l;
• Albumin - the main protein of the body, increases with dehydration, indicators decrease with problems with the liver, intestines, kidneys. Norm - g / l;
• Urea, creatinine, uric acid - are the end products of protein metabolism, are completely excreted by the kidneys, so their increase indicates diseases of the genitourinary system;
• Potassium, sodium, chlorine - blood electrolytes, maintain water-salt balance;
• CRP (C-reactive protein) is a blood element that reacts faster than other indicators to inflammation and tissue damage. The higher the protein, the more acute the inflammation. Norm - up to 5 mg / l;
• Iron - is found in the blood serum, is involved in the transport of oxygen. This indicator changes with diseases of the hematopoietic organs. The norm for women is 8.9-30.4 mmol / l, for men - 11.6-30.4 μmol / l.

The research indicators are quite reliable and are used in various fields of medicine: therapy, surgery, urology, cardiology, gynecology and others.

Preparation for blood collection

No special preparation is required for the analysis. However, in order for the result to be more reliable, some rules must be observed:

• The study is done on an empty stomach, the last meal no later than 12 hours;
• Eliminate alcohol for a week;
• Smoking - one hour before the procedure;
• On the eve, exclude strong physical exertion and stress.
• If the patient is taking hormones or non-steroidal anti-inflammatory drugs, inform the doctor.

The norm of transaminases in the blood

Indicators of transaminases in men

Men have higher enzymes than women. This is because men are more enduring and have more muscle mass.

The norm of ALT and AST in the blood in men:

Men are more likely to violate a healthy lifestyle, proper nutrition, with the help of bad habits they try to overcome stress and nervous shocks, as a result of which they are more likely to be at risk of various diseases.

The norm of ALT, AST in the blood of women and men after 50 years

As we age, body tissues can change. In this regard, the levels of enzymes in the blood increase. Risk factors for increasing aminotransferases in the body after 50 years are:

• Heredity;
• Transferred hepatitis or contact with the patient;
• Virus carriers of various forms of hepatitis;
• Alcohol consumption;

• Taking strong drugs;
• Diabetes;
• The presence of excess weight.

ASAT and ALAT values ​​during pregnancy

Enzyme indicators are measured in arbitrary units, in some clinics other units of measurement are used, when deciphering, one should take into account how the results are translated into other measurement systems.

The accuracy of a blood test for transamnasis norms in pregnant women depends on the equipment on which it is produced, therefore only a specialist can judge the significance of the result.

The norm of AST and ALT in women during pregnancy may differ from the usual level of enzymes in the blood and vary depending on the period. The reason is the altered hormonal background. In the first and last trimester, the concentration of enzymes in the blood increases. The excess can be several times. An increase in aminotransferases tenfold indicates the presence of a serious illness.

Table of normal values ​​of enzymes in women in the 1st and 2nd half of pregnancy:

What are ALT and AST? What does the level of liver enzymes indicate and what are the normal values ​​for women?

AST and ALT are marker enzymes necessary for determining liver pathologies. Ast and Alt are located in the cells of different organs and enter the bloodstream only when they are destroyed. Transferase levels increase during pregnancy, with liver pathology, after a course of certain medications, or after physical activities. Transferases are determined by a biochemical blood test, which is considered the most informative for detecting liver diseases at an early stage.

The peculiarity of the development of liver diseases is that they develop painlessly. The liver does not hurt, because there are no nerve endings in it. Pain in the right hypochondrium, after which a person usually goes to the doctor for the first time, is caused by pathologies of the gallbladder. Only regular blood biochemistry tests during the medical examination will reveal liver pathologies while they have not yet reached the point of irreversibility.

What is ALT (Alt)?

ALT acts predominantly in the cytoplasm of hepatocytes, in the epithelium of the renal glomeruli, and slightly less in the heart. During the developing destructive processes on cellular level Alt from them is released and penetrates into the bloodstream, where its increase is detected. The growth of ALT directly depends on the degree of damage to the organ and is an important indicator of necrotic changes in the tissues of the organ.

In viral hepatitis, the degree of increase in Alt is proportional to the duration of the disease. At acute course disease activity of the enzyme exceeds the norm ten times or more. Alt growth at viral form comes to light very early - even before manifestation of jaundice. Its activity is also increasing in those suffering from the anicteric form. With the effective course of therapy, ALT gradually decreases. However, a rapid decrease in Alt with increasing hyperbilirubinemia is a symptom of an unfavorable course of the disease.

In some cases, Alt may rise for no apparent reason. Also, ALT values ​​change in a healthy person during the day: lower concentrations are recorded early in the morning, larger ones in the afternoon.

What is AST?

AST is present in the liver, in the heart, and to a lesser extent in the kidneys. Determination of Ast is also necessary to identify inflammatory processes in the above organs. A simultaneous increase in transferases always signals damage to hepatocytes - the main liver cells. AST is less sensitive than ALT in organ pathologies.

Alt and Ast norm in women (table by age)

For research, venous blood is taken in the morning on an empty stomach. Serum and plasma are analyzed in the laboratory.

Age table:

With age, the level of transferases gradually decreases. For example, upper bound ALT in healthy women after 50 reaches 28 U / l, and by old age it varies from 5 to 24 U / l.

There are some factors that can affect the transferases of a healthy woman, causing them to fluctuate within 30%. What are these factors:

• 1 trimester of pregnancy;
• excess body mass index;
• alcohol and drug use;
• taking certain medications;
• stress, emotional arousal.

The influence of all these factors (except pregnancy, of course, and obesity) must be minimized before taking the test so that you do not have to retake it a second time. In addition, it must be taken into account that different laboratories may use different tests for research with different standards. In this case, the patient is given a form containing norms in a different measurement system.

Isolated change in ALT

ALT is also activated when released from destructively altered cells. Typically, ALT growth is caused by:

• liver diseases - viral and alcoholic hepatitis, fatty hepatosis, cirrhosis, cancer;
• heart disease - heart attack (slightly), myocarditis, and other diseases that occur with the destruction of myocardial cells;
• severe poisoning and extensive burns, as well as injuries with damage to muscle tissue;
• acute pancreatitis;
• autoimmune thyroiditis;
• intrahepatic cholestasis:
• myositis.

Elevated ALT is recorded in obesity (2-3 times), with progressive leukemia, and cancer.

Isolated change in AST

AST shows the highest activity (100 times higher than normal) in case of toxic damage (in case of poisoning with household chemicals, pale toadstool, etc.). Ast increases with liver cancer and metastasis to this organ, inflammation of viral and autoimmune origin.

AST also increases with:

• heart disease - heart attack and acute rheumatic heart disease, cardiac surgery and angiography, myocarditis, rheumatic heart disease, angina pectoris;
• liver diseases - hepatitis, cirrhosis, oncopathology;
• TELA;
• cholestasis;
• injuries, burns, muscular dystrophy;
• renal failure;
• pancreatitis.

In general, the activity of this enzyme is lower in women than in men. In the older age group and in the 60s, developing cardiac pathologies are a common cause of an increase in AST.

With a heart attack, AST rises 2-20 times, and even before the appearance of its signs on the electrocardiogram. If on the 3rd day of infarction AST does not decrease, the prognosis is poor. An increase in Ast may indicate both the expansion of the infarction focus and the involvement of other organs. With a heart attack, the amount of ALT increases slightly.

Simultaneous level increase

The simultaneous determination of ALT and AST is considered more informative. There is a so-called Ritis ratio (DRr): AST/ALT ratio. Normally, this indicator is 1.33 (this figure should be obtained if the AST value is divided by ALT in a healthy person: the indicator decreases with liver pathologies and increases with cardiac diseases. The error for a healthy person should be no more than 0.42. If the Ritis index does not meet the standard:

• equal to 1 - chronic and dystrophic pathologies of the liver;
• less than 1 - viral hepatitis;
• more than 2 - a heart attack if albumins are normal or alcoholic liver damage if albumins are elevated.

Indications for ALT and AST tests

The doctor prescribes a study of the level of transaminase in case of suspicion of liver pathology. What symptoms should a woman pay attention to in order to visit a doctor:

• pain in the side on the right or a feeling of heaviness in this area;
• icteric skin;
• itching (back, feet, palms);
• frequent nausea and vomiting;
• blood clotting disorder;
• failure of the menstrual cycle;
• poor sleep, irritability, frequent allergic reactions.

Once a year, you need to donate blood for AST / ALT to people who are at risk:

• alcoholics and drug addicts;
• in contact with hepatitis virus carriers;
• working in hazardous production;
• with burdened heredity.

Be sure to check for liver enzymes donors before blood donation.

AsAT and ALT tests are usually considered in conjunction with:

For the diagnosis of cardiac diseases, in addition to the analysis for biochemistry, an ECG is performed.

In addition to biochemistry, separate liver tests are prescribed to determine the functionality of the liver. Liver function is usually assessed by 3 parameters: damage to hepatocytes, cholestasis (bile retention), pathology of the formation of certain substances. Tests are combined according to these parameters, their standard includes:

• AST and ALT - to determine the degree of damage to hepatocytes;
• ALP (alkaline phosphatase) and GGT (gamma glutanyl transferase) are markers of bile stasis;
• bilirubin;
• total protein and albumin - indicators are interconnected with the synthetic function of the liver.

How to donate blood?

In order to have no doubts about the truth of the indications for donating blood for AST, ALT, you need to prepare. The day before the study, you need to exclude sports training and any increased load, you can not drink alcohol and worry. Dinner should be light without fatty and fried foods. Dinner time should be calculated so that there is nothing to eat for 14 hours before blood donation. You can drink water. Blood donation is done in the morning on an empty stomach. If, according to indications, blood donation is carried out during the day, blood donation should be preceded by at least 4 hours of fasting after a light meal.

Only the attending physician can interpret the results, who is aware of what medications the patient is taking, what kind of lifestyle he leads, and how all this affects the test results.

How to lower AST, ALT?

AST and ALT are one of the most important indicators of the state of the body. An increase in enzymes indicates damage to such important organs as the liver, heart, pancreas, etc. Their decrease occurs gradually after the cure of the underlying disease.

The liver is treated by a Hepatologist. In some cases, a hepatologist may prescribe hepatoprotectors to lower enzyme levels. These include Heptral, Heptol, Hofitol, Essentiale Forte, etc. You need to take them under the supervision of a doctor, strictly according to the instructions.

The norm of ALT and AST in the blood

The norm of ALT and AST in the blood of women has clear boundaries.

These indicators are determined during a biochemical blood test for the diagnosis of various diseases and mean different levels of enzymes in the blood plasma.

The norm of ALT and AST in women

In women, ALT values ​​are considered good if the concentration of these enzymes does not exceed 31 U / l.

The norm of ALT in women in the blood is a value ranging from 20 to 40 units.

The norm of AST in women in the blood of ME.

The presence of deviations of indicators up or down is evidence that certain changes are taking place in the body. If the indicators are increased by 2-5 times, then the increase is considered moderate. An increase of 6-10 times indicates an average increase in results.

If the indicators are 10 times or more higher than the norm, then this is a high increase. As a rule, to find out the causes and correct the results, an individual consultation with a specialist is required with the appointment of additional examinations.

The meaning of the terms ALT and AST

These are types of enzymes from the transferase group, which are widely used in medical practice to detect the level of damage to internal organs.

Normally, only a small part of these enzymes enters the bloodstream. In the presence of certain pathologies, these enzymes are determined in the blood to a lesser or greater extent from the norm, which is determined by laboratory methods.

The level of ALT in the blood of a woman allows you to find out the presence and extent of liver damage. The level of AST allows you to assess, in addition to the state of the liver, the degree of damage to the heart muscle.

Causes of increased enzyme levels

Depending on the age of a woman, certain disorders in the tissues of the body may occur. In the future, this leads to the presence of overestimated ALT and AST.

Only a specialist can determine the cause of the increase, based on research.

Isolated increase in ALT

The main reason for the increase in ALT in women is the presence of liver diseases - hepatitis, cirrhosis of the liver, liver cancer. Also causes at any age are diseases of the pancreas, heart disease, diseases of the skeletal muscles and muscles, hypothyroidism. An important role in the list of causes is also occupied by injuries of the body, shock conditions and the presence of burns.

Isolated increase in AST

The most common reason for detecting an elevated level of AST is the presence of heart pathologies in a woman, which increase with the age of older people.

When a myocardial infarction occurs, AST usually rises tenfold. Also, the increase in results is affected by the presence of such diseases as hepatitis, cirrhosis and liver cancer, obstruction of the biliary tract, acute pancreatitis.

Reasons for Simultaneously Increased Enzyme Levels

The simultaneous determination of the level of ALT and AST in the blood of a woman is considered a more informative and reliable result, showing the level of damage to internal organs.

In medical practice, there is the de Ritis coefficient, which indicates the ratio of ALT / AST. Normally, this coefficient is 1.3. With heart disease, the coefficient is detected above the norm, and with liver pathology - below.

After an attack of myocardial infarction, there is a simultaneous increase in ALT and AST, but AST increases by about 10 times, and ALT by about 2 times.

A simultaneous increase in these indicators can be in the absence of external signs - this indicates that hepatitis occurs externally without symptoms, but there are active internal processes of liver destruction.

In some cases, a slight increase in results may be in healthy women as a result of stress, physical overstrain and the use of certain medications.

Signs that require mandatory testing:

• The presence of weakness.
• Feeling of prolonged loss of appetite.
• Presence of nausea and vomiting.
• Pain in the abdomen.
• Yellow skin tone and eyes.
• Darkening of the color of urine.
• The presence of a light stool.
• Feeling of itching.

Factors conducive to an increase in signs of ALT and AST after 40 and 50 years:

1. Previous hepatitis or contact with a patient with any form of hepatitis;
2. Alcohol abuse;
3. Hereditary predisposition to diseases of the liver and heart;
4. Taking medications that can adversely affect the condition of the liver;
5. Presence of diabetes or other chronic diseases;
6. The presence of excess weight.

Research as a criterion for diagnosing diseases

A biochemical blood test, including these indicators, is prescribed if the following pathologies are suspected:

• Any diseases of the heart and blood vessels.
• Any pathology of the liver.
• Renal failure.
• various infections.
• Any autoimmune disease.
• Cholelithiasis.
• Pancreatitis - chronic and acute.
• Pathology of the endocrine system.
• Skin diseases accompanied by itching.
• Malignant tumors of any localization.
• Body poisoning.
• Encephalopathy of unknown origin.

In case of unfavorable results of ALT and AST, a pregnant woman is prescribed an additional series of examinations.

Treatment of diseases depending on the results of the analysis

The results of ALT and AST tests are necessary for treatment and health monitoring during and after the prescribed therapy.

ALT and AST indicators are used in preparation for any types of surgical interventions in order to identify contraindications and possible complications.

Also of no small importance is the long-term use of drugs that affect the internal organs - broad-spectrum antibiotics, hormonal agents, chemotherapy drugs.

Rules for passing the analysis

The analysis is carried out in any public clinic and private laboratory.

In order to obtain reliable results of tests for ALT and AST, a woman must adhere to the following rules:

• Do not eat for 8-12 hours before the study.
• Eliminate any physical activity and overexertion 30 minutes before the study.
• Eliminate psychological stress 30 minutes before the study.
• Stop smoking 30 minutes before the test.
• Refrain from drinking alcohol and fried foods a day before the study.
• Warn the specialist about the medications you are taking.

Folk remedies to normalize the level of enzymes in the blood

The indicators of ALT and AST in the body of each woman indicate the presence of her actual health. The norm is ALT - 32 units per liter, AST - from 20 to 40 units per liter, any deviation from the norm in one direction or another is considered a reason for additional examinations in order to identify the presence of diseases of the internal organs. I would also like to note that for women during the period of bearing a child, there are their own ALT and AST values.

Most women, before embarking on rational traditional treatment, usually use folk remedies. It turns out that this is not only possible, but even supported by the attending physicians.

There are a great many recipes for reducing overestimated indicators, the most effective ones are listed below.

1. Milk thistle seed drink. Crushed seeds in the amount of 1 teaspoon pour 200 milliliters of boiling water. The vessel with the contents is tightly sealed and allowed to infuse for 20 minutes at room temperature. Then the infusion is filtered and taken orally 2 times a day, 1 glass half an hour before the main meal. It should be remembered that you can not drink the decoction in one gulp. Course treatment lasts 21 calendar days.
2. Herbal tea. To prepare it, you need to have St. John's wort, immortelle and celandine in the ratio 2:2:1 (tablespoons). Grind the grass, put it in a vessel that can be tightly sealed, pour a liter of boiling water and put it in a dark place for 12 hours to infuse. After the time has elapsed, the infusion is boiled for 10 minutes, and then cooled at room temperature. Next, the broth should be filtered and taken orally 100 milliliters after meals 4 times a day. Course treatment lasts 2 weeks.
3. Dandelion root extract. Pour 200 grams of crushed root with 100 milliliters of vodka and add 30 milliliters of glycerin. Seal the vessel with the contents tightly and place in a dark, cool place for 24 hours. Then strain the infusion and take orally 2 tablespoons before the main meal 3 times a day. The duration of the course of treatment should be discussed with the doctor.
4. Collect hairs from ripe corn cobs. Dry them naturally and grind them. Next, prepare a drink from 1 teaspoon of chopped dry hairs and 200 milliliters of boiling water. It should be kept after pouring for ¼ hour, then strain and take orally 1 glass 2 times a day. Course treatment can last up to six months.

The general opinion of those who took these funds

Before embarking on treatment with folk methods, many patients are interested in the reviews of those people who have already tried these recipes on themselves.

So, the most effective folk recipes for reducing AST and ALT are listed above. Therefore, there are a great many reviews about them, but putting them all together, we get the following picture:

• after taking milk thistle, the indicators were significantly reduced by the second biochemical blood test;
• corn hairs have the necessary effect, but it is not possible to sharply reduce the performance;
• dandelion root infusion is very effective, but it should not be taken if you drive a vehicle, since alcohol is present in the composition;
• herbal tea helps to cope with the situation and after two weeks of daily intake you feel much better, especially since it allows you to strengthen your immune system, but the main inconvenience is its 4-fold use, you have to take it with you in a thermos to work so as not to miss a dose .

Each patient should remember that his body is individual and even with a million positive reviews, the treatment may not be suitable. For example, when taking milk thistle in the first two days, there may be sensations of pain in the liver area - this is the norm, but if this feeling does not leave the person during subsequent treatment, then this fact indicates individual intolerance.

Therefore, starting any treatment, you should strictly monitor the reaction of your body and if you have any questions, you should always consult with your doctor. Since the patient needs to get rid of the disease, and not aggravate the situation.

Possible consequences of elevated enzyme levels if left untreated

Sometimes, it seems to women that they can start treating the disease later, because nothing supernatural will happen in one or two days, and today there is absolutely no time to go to the doctor and prescribe drugs. Of course, if the indicators are not very high, then one day will not play a role, but when the start of rehabilitation is postponed for a month or more, then there is nothing good to expect. The thing is that while a person delays his visit to the doctor, the disease does not doze, but conquers a new large territory.

And before you give up on elevated ALT and AST, you need to know very well what this can turn out to be if left untreated:

• cirrhosis of the liver;
• hepatitis;
• myocardial infarction;
• stagnation of bile and, as a result, intoxication of the body;
• liver oncology;
• hepatosis.

Each of the above diseases, in the absence of measures taken to eliminate it, can provoke a fatal outcome. But in cases of determining its development in the early stages, you can get rid of the disease without dire consequences.

Prevention of the occurrence of an increase in women

Any disease is best prevented than long-term treatment, which is why there is a concept of preventive measures.

In order for the indicators of ALT and AST in the blood of women not to rise to the heights, you should first of all reconsider your entire algorithm of life.

1. Give up bad habits. Alcohol and smoking do not benefit anyone, and the female body is more prone to addiction.
2. Follow nutrition. Avoid fried, salty, spicy and smoked foods. Enrich your diet with raw vegetables and fruits. Get into the habit of having breakfast in the morning not with coffee sandwiches, but with porridge with tea or jelly.
3. Avoid unnecessary stress. In cases where, nevertheless, fate has presented an unpleasant surprise, then perhaps you should drink a course of sedatives, rather than drive yourself into a trap.
4. Take as a basic rule - to be in the fresh air for at least 2 hours a day. If it doesn't work during the daytime, then it should be evening walks.
5. Make a daily routine and stick to it. Only the correct alternation of work and rest of the body will allow a woman to save it.
6. Have a permanent sexual partner. Promiscuity in intimate relationships can be a provocateur of the development of various kinds of diseases and, as a result, an increase in ALT and AST.
7. Periodically donate blood for analysis and monitor your ALT and AST levels (at least once every six months), especially after reaching the age of 35.

All these simple rules, if followed, will allow a woman to maintain her own health, which means that the ALT and AST indicators will remain within acceptable values.

The appointment of treatment for a particular disease is preceded by its diagnosis. In some cases, it is not necessary to conduct a complete examination of the patient, it is enough just to pass a series of tests. The list of such often includes a biochemical blood test. Indicators of AST and ALT in blood biochemistry are key in assessing the patient's condition.

What is AST and ALT in a blood test

AST - aspartate aminotransferase is an enzyme that ensures the exchange of a special amino acid (aspartate) between biological molecules. The AST enzyme is most active in the human heart, kidneys, liver and muscles.

ALT and AST levels can be detected using a biochemical blood test.

ALT - alanine aminotransferase - is an enzyme that helps move the amino acid alanine from one molecule to another. The enzyme is most active, in addition to the above organs, in the human pancreas. ALT and AST in a blood test

Thus, AST and ALT are active participants in amino acid metabolism in the body. Enzymes “live” exclusively in the tissues of organs; they end up in the blood due to cell destruction during the development of a disease or injury.

It is possible to determine the content of these enzymes in the patient's blood using a biochemical analysis.

What are the benchmarks?

A standard unit is a measure of measuring the concentration of enzymes in the patient's blood. Calculating their exact number using mathematical methods is impossible even with the condition of working on advanced equipment. The verdict is based on the level of enzyme activity.

The normative indicator of AST and ALT in certain groups of the population is individual

Features during pregnancy and lactation

In the first two trimesters, the level of AST and ALT may decrease slightly - by 5-10%. This is due to the increased work of the liver. In the third, the indicators should be as close as possible to the norm. In the case of AST, its slight increase after childbirth is possible, which is caused by active muscle work during labor.

Factors affecting the reliability of the results

There is a group of factors that can affect the reliability of the results of biochemistry, as a result, ALT or AST values ​​are outside the normal range. Among those:

• intensive sports;
• taking medications (sedatives, antibiotics, contraceptives, etc.);
• passion for fatty or fried foods;
• excessive consumption of alcoholic beverages;
• transferred stress;
• injury.

Before passing the analysis, the above factors should be excluded.

Symptoms and causes of deviations from the norm

Minor deviations from established norms ALT and AST practically do not manifest themselves in any way and indicate malfunctions in the functioning of the liver.

Among the most common reasons for an increase in the concentration of enzymes:

• fatty hepatosis;
• reaction to medication;
• serious injury;
• development of pancreatitis, mononucleosis;
• extensive liver damage (as a result of addiction to alcohol, drugs);
• metastases in the liver.

On early dates increase in performance in the patient observed general lethargy, fatigue. Appetite disappears - body weight decreases. Skin itching, insomnia, nervous breakdown appear.

An increase in the concentration of ALT and AST enzymes may indicate extensive liver damage.

Late symptoms are characterized by:

swelling of the limbs;

yellowness of the skin and eye proteins;

discoloration of urine and feces;

the development of ascites and the increase in signs of intoxication of the body.

Consequences of elevated AST and ALT levels

Even minimally increased activity of enzymes indicates the occurrence of a certain disease. If you do nothing and aggravate circumstances (take alcohol, eat improperly, etc.), you can provoke the development of:

All of these pathologies are quite serious. However, they can be successfully treated if diseases are detected in a timely manner.

State normalization

Medical therapy

In the case of an increase in the activity of enzymes in human blood, specialists resort to prescribing herbal medicines. The drugs have anti-inflammatory and choleretic effects.

At increased rates ALT and AST in a blood test, specialists often prescribe milk thistle

Traditional medicines include:

Milk thistle, available as tablets, capsules, or oil.

The drug Heptral, which has a similar effect.

It is important to know! The dosage and duration of therapy with any drugs are determined by the doctor.

Diet and exercise

Another direction of treatment of the patient is the organization of proper nutrition and cleansing of the body. The patient's diet should contain as many fruits and vegetables as possible. Coffee should be replaced with herbal or green tea. Additionally, you need to consume vitamin C. You should eat often and in small portions.

Maintaining a healthy lifestyle helps to normalize the condition, in particular proper nutrition and regular physical activity.

The following are considered taboo:

fatty foods;

fried;

too salty;

smoked and pickled foods;

fast food;

alcohol;

sweet carbonated drinks.

Regular sports, contrast showers will have a good effect on the patient's body.

Folk remedies

As alternative methods folk methods can be used for treatment:

1. Burdock root decoction. Ground root in the amount of 2 tbsp. l. pour a glass of boiling water, leave in a water bath for 15 minutes. We remove the broth, cover and insist for 2 hours. We filter and take three times a day for 2 tbsp. l.
2. A decoction of calendula flowers. Dry flowers (2 tbsp.) Pour boiling water (400 ml), leave for 2 hours. We filter the broth and take 100 ml three times a day with meals.

It is important to know! Before using folk prescriptions for treatment, you should consult a doctor.

Prevention of elevated AST and ALT levels

You can prevent an increase in AST and ALT by following these recommendations:

• enrich your daily diet with vitamin D, which is found in milk, eggs, apples, sea fish, caviar, buckwheat, oatmeal;
• exclude fried, too salty foods from your menu. This will help unload the liver;
• give up bad habits: drinking alcohol, smoking;
• avoid exposure to toxins that quickly enter the human body and have a detrimental effect on the liver;
• do not self-medicate. Excessive use of antibiotics can be a consequence of liver dysfunction.

More about diabetes:

Enzymes AST and ALT in human blood are involved in the production of amino acids. In a biochemical blood test in women, the norm of ALT and AST is important. Deviation from the norm indicates a malfunction of the body.

This mainly concerns such an important organ as the liver. It performs work on blood purification, metabolism between cells, the functioning of the gastrointestinal tract, the preservation of useful micro and macro elements, the formation of new blood cells. Diseases in the largest gland of the human body often go unnoticed. Ultrasonography liver and a blood test for biochemistry help to detect violations in the work of the organ in time. It is the norm of ALT and AST in the blood that is an indicator of the proper functioning of the body.

What are ALT and AST enzymes?

The enzymes AST and ALT transport atoms between amino acids in the tissues of the human body. In medical practice, two terms are used to denote them: transaminases and aminotransferases. AST transaminase is responsible for the transfer of the aspartic amino acid, ALT-alanine. Each amino acid is carried by a similarly named group of transaminases. Aminotransferases are present in all cells of the body, each fulfilling its purpose.

How is enzyme activity measured?

Indicators of AST and ALT in the blood began to be detected recently. Research is possible in modern laboratories with special equipment. The content of enzymes in the blood is calculated in arbitrary units. The results are determined by the degree of activity of AST and ALT. It is very important to carry out the analysis with great accuracy. If the indicators exceed the norm, a repeated full examination is carried out. To establish a more accurate diagnosis, the following information about the patient's health is collected:

• what preparations and medicines the patient took;
• whether there were liver or kidney diseases in the family;
• whether the patient was treated for hepatitis or jaundice;
• Does the patient have abdominal pain?
• whether there have been significant changes in the body, a sharp loss or gain in weight, oncological diseases, diabetes;
• have ever had blood transfusions;
• whether there was a decrease in libido.

AST and ALT proteins enter the blood when there is a malfunction in any organ. Even a slight excess of enzymes in the blood may indicate the destruction of the cells of the diseased organ. Therefore, the norm in the amount of ALT and AST enzymes in the biochemical blood test in women is so important.

How is the level determined?

AST and ALT values ​​differ between adults and children. The norm in the analyzes for women and men also differs. The number of AST enzymes in women is normally from 20 to 40 conventional units, ALT transaminases - from 30 to 32 units. Due to the difference in the scale of arbitrary units in each laboratory, the level of enzymatic activity indicators is calculated differently. Therefore, it is better to entrust the interpretation of the analyzes to a specialist. A strong deviation from the norm can be the result of a serious illness. An increase in indicators from 2 to 5 times is considered insignificant, from 6 to 10 average, more than 10 high.

What are the symptoms of an increase?

The amount of enzymes in the blood increases with diseases:

• acute viral hepatitis;
• liver intoxication;
• liver cancer;
• destruction of muscle fibers, necrosis of skeletal muscles;
• myocardial infarction.

The result of the analysis may deviate from the norm, not only due to a serious illness. An increase in alanine aminotransferase can be caused by taking aspirin, paracetamol, and hormonal contraceptives.

also products containing echinacea and valerian change the results of indicators in the blood. Before a biochemical analysis for ALT and AST, the doctor must be aware of the use of such drugs. Taking statins for high cholesterol causes an increase in the ALT enzyme. Changes in indicators may occur due to a malfunction in the gastrointestinal tract. Improper nutrition and diseases of the liver and heart are the main reasons for the increase in AST and ALT in the blood. In liver disease, cells are destroyed. In this case, a person experiences bitterness in the mouth, weakness, pain in the right hypochondrium, the skin color becomes yellowish.

In the first trimester in pregnant women, the amount of enzymes in the blood is slightly higher than normal. But if the level of transaminases is stable, this is not a cause for concern. In the later stages, a deviation from the norm of AST and ALT may indicate preeclampsia. Due to the heavy load on the liver, the body can not cope. A pregnant woman may experience dizziness, weakness, and increased blood pressure.

What are the reasons for the increase?

The main reasons for the increase in transaminases in the blood test can be identified:

• frequent consumption of fatty foods, malnutrition;
• taking strong drugs - statins, antibiotics, barbiturates;
• muscle breaks;
• alcohol abuse;
• violation of the rules when taking an analysis, when taking blood;
• increase in physical and emotional stress;
• performing heart surgery or other surgical intervention;
• a course of chemotherapy;
• malignant tumor;
• severe overweight;
• taking drugs;
• lead poisoning;
• infectious disease mononucleosis, causing a change in the composition of the blood and destruction of the liver and spleen;
• hepatitis.

How is diagnosis and treatment carried out?

Enzyme levels can be brought back to normal by eliminating the causes of the deviation. Most often this occurs due to liver and heart disease. After completing the course of treatment, AST and ALT should be at the right level. People aged and with chronic diseases should regularly monitor the rate of ALT and AST by donating blood for biochemical analysis. Thus, it is possible to track the appearance of failures in the body in a timely manner.

It is necessary to refuse long-term use of potent drugs, start eating right and lead a healthy lifestyle. It is important to consume a large number of vegetables, fruits, green tea, herbal infusions. Infusions from the herb of milk thistle, dandelion, burdock help well. They have a beneficial effect on the liver, remove toxins, and help cleanse the body as a whole. Gymnastics, hardening, playing sports - play an important role in maintaining health at the proper level.

Cleansing the body is useful for diabetes and other chronic diseases. Prevention has a positive effect on healthy person. Helps to save normal performance blood test. It is important to remove the foci of inflammation in the body and maintain normal levels of AST and ALT.

You should abandon the use of potent drugs in favor of herbal medicines. Such drugs are called hepatoprotectors. They take over the partial functions of the liver. They help cleanse the body, remove toxins and toxins, participate in the process of metabolism between cells, unloading a weakened liver. Thus, they help stop the destruction of the organ and allow you to restore the proper functioning of the gland, without affecting the rest of the organs of the human body.

The substance is an enzyme that facilitates the transport of amino acids within the human body. AST (synonyms AST, AST) is present in the cells of the whole organism, but most of all it is observed in the liver and heart, slightly less in muscle tissue, kidneys, spleen and pancreas.

The function of the enzyme also includes participation in the production of bile, the production of the necessary protein structures, the conversion of nutrients, the breakdown of toxic compounds. The norm of the state of the blood provides for a minimum amount of the enzyme in the bloodstream, with a change in the level, it can be assumed that there is a serious pathology. A change in the value of ASAT is noted earlier than specific symptoms diseases.

Increasing the indicator

An elevated AST level is observed in a person if the following phenomena are present:

• Liver pathologies (from hepatitis to cirrhosis and cancer);
• Disorders in the work of the heart (heart attack, failure of the heart rhythm);
• Thrombosis of large vessels;
• The appearance of areas of necrotization (gangrene);
• Injuries ( mechanical damage muscles), burns.

The reasons for the low increase in AST may indicate a significant physical activity or recent injection or oral use of a drug, vaccine, or vitamin.

Decrease in indicator

Diagnostic value has not only an increased level of AST, but also its decrease. Liver ruptures are cited as the most common cause of the condition, but the value may fluctuate downward during pregnancy or a lack of vitamin B6, which is involved in the transport of aspartate.

Normal value

The norm of the AST level differs depending on the research methodology. The results obtained with different methods of determination cannot be compared with each other. Please note that the test system is indicated by the laboratory in the analysis form. This also means that each laboratory has its own reference values, which may differ from the norms adopted in other laboratories.

Result AU 680

For children under the age of one month, the AST norm is 25–75 units per liter. In older patients (up to 14 years of age), the average range is 15–60.

In adult men and women, the norm is different:
For men - 0-50.
For women - 0-45.

The AST indicator is also recalculated per liter of blood and is measured in arbitrary units:

Alanine amino transferase

ALT (synonyms ALT, ALT), like AST, is an enzyme, but alanine amino transferase is responsible for moving the amino acid alanine from one cell to another. Thanks to the enzyme, the central nervous system receives energy for its work, immunity is strengthened, metabolic processes are normalized. The substance is involved in the formation of lymphocytes. Normally, ALT is present in the blood in small amounts. The highest concentration of the enzyme is observed in the tissues of the liver and heart, a little less - in the kidneys, muscles, spleen, lungs and pancreas. A change in the content of ALT in the blood is observed in serious diseases, but can also be a variant of the normal state.

Increasing the indicator

In a biochemical blood test, ALT can be elevated as a result of the following pathologies:

• Damage to the liver and biliary tract (hepatitis, cirrhosis, cancer, obstruction);
• Intoxication (alcoholic, chemical);
• Diseases of the heart and blood vessels (ischemia, heart attack, myocarditis);
• Blood diseases;
• Trauma and burns.

The ALT value may increase after taking medications, eating fatty foods or fast food, intramuscular injections.

Decrease in indicator

In a biochemical blood test, a decrease in the ALT index may be observed, this indicates a lack of vitamin B6 involved in the transport of alanine, or severe pathologies liver: cirrhosis, necrosis and others.

Normal value

Like AST, ALT in the blood is determined by several methods, the laboratory indicates it in the test result form. Studies performed using different methods cannot be compared with each other.

Result AU 680

In children under one month of age, the ALT norm is 13–45 units per liter of blood.

In children older than one month and adults, normal ALT values ​​vary by gender:

• Men - from 0 to 50 units;
• Women - from 0 to 35 units.

Result Cobas 8000

According to this test system, the value of the norm of the indicator depends on the age of the person and his gender:

All values ​​are indicated in units per 1 liter of blood.

When is a study ordered?

The doctor may order a biochemical analysis to study the level of AST and ALT enzymes if there are signs of liver damage or some factors that can affect its work.

Common symptoms of liver disease:

• loss of appetite;
• cases of vomiting;
• The presence of a feeling of nausea;
• Pain in the abdomen;
• Light color of feces;
• Dark color of urine;
• Yellowish hue of the whites of the eyes or skin;
• The presence of itching;
• General weakness;
• Increased fatigue.

Risk factors for liver damage:

• Alcohol abuse;
• Hepatitis or previous jaundice;
• The presence of liver pathology in close relatives;
• Taking potentially toxic drugs ( anabolic steroid; anti-inflammatory, anti-tuberculosis, antifungal medicines; antibiotics, etc.)
• Diabetes;
• Obesity.

An analysis of AST and ALT enzymes can be performed to assess the effectiveness of treatment (if the elevated level gradually decreases, they are diagnosed positive effect from drug therapy).

Features of diagnostics

For diagnostic purposes, not only the fact of changes in the blood parameters of AST and ALT is important, but also the degree of their increase or decrease, as well as the ratio of the number of enzymes to each other. Eg:

An increase in both indicators (AST and ALT) in the analysis by 1.5–5 times indicates myocardial infarction.

If the ratio of AST / ALT is in the range of 0.55–0.65, it can be assumed that viral hepatitis is in the acute phase; an excess of 0.83 indicates a severe course of the disease.

If the AST level is much higher than the ALT level (the AST/ALT ratio is much greater than 1), then alcoholic hepatitis, muscle damage, or cirrhosis may be the cause of such changes.

To exclude errors, the doctor must also evaluate other blood parameters (in the case of liver pathology, this is bilirubin-amino-transferase dissociation). If there is an increased level of bilirubin against the background of a decrease in the level of the enzymes in question, then it is assumed acute form liver failure or subhepatic jaundice.

Rules for the delivery of a biochemical blood test

Failure to comply with the rules for preparing for analysis may lead to knowingly obtaining false results, which will entail the need for additional examination and a long procedure for clarifying the diagnosis. Preparation includes several main points:

1. Delivery of the material is carried out on an empty stomach in the morning;
2. Exclude fatty, spicy foods, alcohol and fast food the day before donating blood;
3. Do not smoke half an hour before the procedure;
4. Eliminate physical and emotional stress the night before and in the morning before blood sampling;
5. You should not take the material immediately after radiography, fluorography, physiotherapy, ultrasound or rectal examination;
6. Tell your doctor about all you are taking medicines, vitamins, biologically active additives and vaccinations before the appointment of a biochemical study.

Diagnosis of diseases according to the results of a blood test - complex process, requiring the availability of relevant knowledge, therefore, the interpretation of the results must be entrusted to qualified doctors.

ALT and AST: what is it? What does an increase in the level of ALT and AST in the blood mean? How to take the analysis?

ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are special proteins (enzymes) that are contained inside the cells of the body and are involved in the metabolism of amino acids (substances that make up proteins). These enzymes are found only in the cells of various organs and enter the blood when damaged or cell destruction (disease, injury). Elevated levels of ALT and AST indicate the presence of a disease of one or another organ (most often hepatitis, pancreatitis, heart attack). The content of ALT and AST in different organs is not the same, therefore, an increase in one of these enzymes may indicate a disease in a particular organ.

ALT (ALAT, alanine aminotransferase) is an enzyme that is found mainly in the cells of the liver, kidneys, muscles, heart (myocardium - heart muscle) and pancreas. When they are damaged, a large amount of ALT is released from the destroyed cells, which leads to an increase in its level in the blood. AST (AST, aspartate aminotransferase) is an enzyme that is also found in the cells of the heart (in the myocardium), liver, muscles, nerve tissues, and to a lesser extent in the lungs, kidneys, pancreas. Damage to the above organs leads to an increase in the level of AST in the blood.

What are the norms for the content of ALT and AST in the blood?

Determination of the level of ALT and AST is carried out using a biochemical blood test. In order to obtain reliable results of the study, it is recommended to donate blood for biochemical analysis in the morning, on an empty stomach (it is recommended not to eat anything for at least 8 hours before taking the analysis). Blood is usually taken from a vein. Normally, the blood levels of ALT and AST in men and women are not the same. In women, this level normally does not exceed 31 units / l. In men, normal ALT does not exceed 45 U / l, and AST 47 U / l. In children, the level of ALT and AST varies depending on age, but should not exceed for ALT - 50 U / l, for AST - from birth to 5 days up to 140 U / l, up to 9 years - up to 55 U / l. It is important to take into account the fact that the norms and reference values ​​​​of ALT and AST transaminases vary depending on the equipment that the laboratory has, therefore, only a doctor who knows the norms of the laboratory can interpret the results of the analysis.

Why is ALT elevated?

High ALT indicates diseases of those organs in the cells of which it is contained in the greatest quantities. There are the following main reasons:

1. Hepatitis and other liver diseases (liver cirrhosis, fatty hepatosis - replacement of liver cells with fat cells, liver cancer, etc.) In viral hepatitis A, B, C, D and E, as well as other forms of hepatitis (drug-induced, alcoholic hepatitis, etc. ) many liver cells are destroyed, causing ALT to pass from the liver cells into the blood. Other symptoms of hepatitis are: pain and discomfort in the right hypochondrium, jaundice (yellowing of the skin of the body, sclera of the eyes and mucous membranes), bitter belching, bloating, constipation, diarrhea, etc. In a biochemical blood test, against the background of hepatitis, in addition to ALT, as a rule , there is an increase in the level of bilirubin (blood pigment). Often, an increase in ALT precedes the onset of other symptoms of the disease. The degree of elevation of ALT blood levels in hepatitis is generally proportional to the severity of the liver disease.
2. Myocardial infarction is the necrosis (death) of a section of the heart muscle, as a result of which ALT and AST are released into the blood. Thus, with myocardial infarction, the level of both enzymes in the blood increases. Other symptoms of myocardial infarction are: acute pain in the region of the heart, radiating to the left side of the body ( left side neck, inner surface left hand, etc.), prolonged pain (lasting more than 30 minutes), shortness of breath, feeling of weakness, fear of death, dizziness, etc.
3. Other heart diseases (myocarditis, heart failure, etc.) that occur with the destruction of myocardial cells (heart muscle) are also accompanied by an increase in ALT in the blood. Other symptoms of these diseases are: shortness of breath, palpitations, decreased blood pressure and etc.
4. Acute pancreatitis is inflammation of the pancreas. With pancreatitis, the level of ALT in the blood rises. Other symptoms of the disease are: pain around the navel, diarrhea, bloating, weight loss, etc.

Why is AST elevated?

An increase in the level of AST, as a rule, indicates diseases of the heart, liver, pancreas, etc. There are the following main causes:

1. Myocardial infarction is the most common cause increase in the level of AST in the blood. At the same time, AST, as a rule, is increased several times, while the level of ALT is slightly increased. Other symptoms of myocardial infarction: an attack of acute prolonged pain in the region of the heart, weakness, shortness of breath, dizziness, etc.
2. Other heart diseases (myocarditis, rheumatic heart disease - inflammation of the heart with rheumatism), as well as conditions after a recent operation, cause an increase in the level of AST in the blood.
3. Liver diseases (viral hepatitis, alcoholic, drug, toxic hepatitis, cirrhosis of the liver, liver cancer, etc.) are often the cause of an increase in the blood level of both enzymes.
4. Major injuries, burns.

Decrease in the level of ALT and AST in the blood.

An excessive decrease in the level of ALT and AST in the blood is a serious condition and often indicates the presence of severe liver damage (cirrhosis, etc.)

Increased ALT during pregnancy.

In the first trimester of pregnancy, a slight increase in ALT is common and does not indicate the presence of diseases. A significant increase in the level of ALT and AST in the blood of a pregnant woman requires a thorough examination for the presence of liver disease.

How to lower the level of ALT and AST?

ALT and AST - what is it?

• ALT= ALT = AL anin aminotransferase
• AST= ASAT = AC partat aminotransferase

Aminotransferases, they are transaminases - this is intracellular enzymes, which are involved in the metabolism of amino acids and carbohydrates.

Enzymes ALT and AST– catalyze, i.e. accelerate intracellular transamination reactions. The coenzyme pyridoxine=vitamin B 6 stimulates their catalytic activity.

- transfer of the amino group NH 2 from the amino acid to the α-keto acid. The result is a new amino acid and a new a-keto acid.

Aminotransferases "work" inside every living cell. With programmed natural cell death, their contents enter the blood in small quantities. The active death of many cells leads to a massive influx of intracellular enzymes into the blood and, accordingly, to a significant increase in their level.

A high level of active ALT and AST enzymes in blood plasma is an indicator of a pathological process or disease that leads to cell destruction and tissue necrosis.

ALT (ALAT)- participates in the breakdown of the amino acid alanine, predominates in hepatocytes.

ALT, due to its high content in liver cells, is often called liver enzyme . But ALT in sufficient concentrations is found in the kidneys, myocardium, skeletal muscles, nervous and other tissues. Their damage also leads to an increase in the level of this enzyme in the blood.

AST (AST)- participates in the breakdown of aspartic amino acids, predominates in cardiac muscle cells.

AST is found in certain amounts in skeletal muscle and other tissues. When they are destroyed, the level of the enzyme in the blood increases, but to a lesser extent than with necrosis of the heart muscle.

ALT is a marker of acute diseases of the liver and biliary tract.
AST is a marker of myocardial destruction.

The norm of ALT and AST in the blood

Methods for determining the activity of aminotransferases (transaminases) in different laboratories are different. Each has its own reference limits and units of measurement.

For a more accurate interpretation of the data, it is better to use the norms provided by the local laboratory.

Reference values ​​of ALT and AST

Diseases in which the level of ALT and AST in the blood increases

In acute hepatitis, ALT increases to a greater extent. In the pathology of the heart and skeletal muscles, AST increases to a greater extent.

Hepatitis:
- acute vyrusny (A, B, C, E, F, herpesvirus);
- chronic viral (B or C);
- toxic, alcoholic;
- medicinal;
- bacterial;
- autoimmune;
- steatohepatitis - inflammation of the liver, against the background of its fatty degeneration.

• Cholangitis, intrahepatic cholestasis, obstruction of the biliary tract.
• Primary liver tumors (liver carcinoma).
• Metastases cancerous tumors into the liver.
• Pancreatitis is acute.
• Cirrhosis of the liver.
• Infectious mononucleosis.
• Hemochromatosis is hereditary pigmentary cirrhosis of the liver.
• Hemophilia.

Chemotherapy:
a high level of aminotransferases can be observed both during treatment and 1-3 months after chemotherapy.

Myocardial infarction.
Diagnostic value of AST: in case of a heart attack, the content of AST in the blood increases by 2-20 times on the 2nd-3rd day after a painful attack. With angina pectoris, AST and ALT are normal.

• Myocarditis.
• Myositis.

Crash syndrome, destruction of skeletal muscles, physical overload, mechanical (burns, injuries) or ischemic tissue destruction (heat stroke, ischemic stroke).

• Wilson-Konovalov disease is a congenital hepatocerebral dystrophy.

Celiac disease is an autoimmune-allergic lesion of the intestinal mucosa.

• Hyperthyroidism.
• Obesity, metabolic syndrome.
• Deficiency of a-1-antitrypsin.

In children in infancy, the level of ALT and AST in the blood may exceed the norm - this is not a pathology.

Interpretation of ALT and AST values

Interpretation of high values ​​of ALT and AST by the de Ritis coefficient

De Ritis ratio (KDR) is the ratio elevated blood levels of AST and ALT.

De Ritis coefficient:

KDR = AST / ALT

In the case of normal AST and ALT values, the information content of KDR is negligible.

Calculation of the de Ritis coefficient

What drugs increase the level of ALT and AST in the blood?

Self-medication, uncontrolled, unjustified intake of medicines, dietary supplements, herbal preparations, can provoke toxic hepatitis. Alcohol abuse, drug use, poisoning with poisons, heavy metals also lead to toxic damage to hepatocytes and an increase in the level of transaminases in the blood.

Drugs that increase ALT and AST in the blood:

- antibiotics;
- nitrofurans;
- fluoroquinolones;
- antifungal drugs;
— anticonvulsants;
- statins;
- NSAIDs;
- heparin;
- hypoglycemic drugs (sulfonylurea drugs).

Decreased activity of ALT and AST

The complete absence or scanty content of active aminotransferases in the blood indicates pyridoxine deficiency (vitamin B 6).

The main food sources of vitamin B 6 are:

- sprouts of grain crops;
- walnuts, hazelnuts;
- spinach, carrots, cabbage;
- beans, soybeans, other legumes, cereals;
- tomatoes, strawberries, cherries, oranges, lemon.
- meat, dairy products, fish, eggs.

What does an increase in ALT and AST mean in pregnant women

A high level of estrogen in the blood of pregnant women affects the liver cells, so a slight increase in the level of aminotransferases in the blood of pregnant women is not considered a pathology.

In some cases, an increase in the activity of ALT and AST in pregnant women indicates preeclampsia - late toxicosis of pregnancy. This condition is dangerous for the expectant mother and requires urgent treatment.

During pregnancy, the body's need for vitamin B6 increases two and a half times. An unbalanced diet can lead to a decrease in the activity of ALT and AST.

How to donate blood for ALT and AST

The level of aminotransferases in the blood is determined by biochemical analysis. Blood is taken from a vein in the morning, strictly on an empty stomach- do not eat at least 8, but not more than 14 hours before donating blood.

According to the results of a biochemical analysis in the blood, ALT and AST are elevated - then consult a doctor for further examination. After identifying the pathology and correct treatment, the level of enzymes in the blood will return to normal on its own.

What does an increase in ALT and AST above normal mean?

In adults, the content of ALT and AST in different organs is not the same, so an increase in one of these enzymes may indicate a disease in a particular organ.

• ALT (ALAT, alanine aminotransferase) is an enzyme that is found mainly in the cells of the liver, kidneys, muscles, heart (myocardium - heart muscle) and pancreas. When they are damaged, a large amount of ALT is released from the destroyed cells, which leads to an increase in its level in the blood.
• AST (AST, aspartate aminotransferase) is an enzyme that is also found in heart cells (in the myocardium), liver, muscles, nerve tissues, and to a lesser extent in the lungs, kidneys, and pancreas. Damage to the above organs leads to an increase in the level of AST in the blood.

Basically, the rate of ALT and AST in the blood depends entirely on the work of the most important parenchymal organ - the liver, which performs such functions as:

1. Protein synthesis.
2. Production of biochemical substances necessary for the body.
3. Detoxification is the removal of toxic substances and poisons from the body.
4. Storage of glycogen - a polysaccharide, which is necessary for the full functioning of the body.
5. Regulation of biochemical reactions of synthesis and decay of most microparticles.

Depending on the equipment used for the study, it is possible to vary the norms and reference values ​​of the level of enzymes. An increase in the rate of enzyme renewal, cell damage leads to an increase in the level of transaminases in the blood.

Reasons for increasing ALT and AST

Why are ALT and AST elevated in adults, what does this mean? Most probable cause elevated levels of liver enzymes in the blood are:

1. Hepatitis and other liver diseases (liver cirrhosis, fatty hepatosis - replacement of liver cells with fat cells, liver cancer, etc.).
2. Increased ALT and AST as a result of diseases of other organs (autoimmune thyroiditis, mononucleosis).
3. Myocardial infarction is the necrosis (death) of a section of the heart muscle, as a result of which ALT and AST are released into the blood.
4. Diffuse liver damage, which may be caused by alcohol, drugs and/or exposure to a virus.
5. Extensive injuries with muscle damage, as well as burns, cause an increase in ALT in the blood.
6. Acute and chronic pancreatitis.
7. Metastases or neoplasms in the liver.
8. Reaction to drugs.
9. Taking anabolic steroids.

AST and ALT are important indicators of the state of various organs. An increase in these enzymes indicates damage to organs such as the liver, heart, muscles, pancreas, etc. Thus, a decrease in their level in the blood occurs independently when the underlying disease is eliminated.

Prevention

In order to ensure that the norm of indicators does not exceed the permissible limits, it is recommended to avoid long-term receptions medicines.

If this is not possible due to chronic disease, then it is better to regularly take an analysis for AsAT so that it is not increased or a serious increase is prevented in time. Periodically, you need to visit a gastroenterologist and a hepatologist who can identify a possible disease and prescribe treatment.

What to do if ALT and AST are elevated

In order to quickly and objectively understand the true reason for the increase in the levels of activity of ALT and AST enzymes, it is necessary to additionally pass biochemical tests.

First of all, it is advisable to determine the levels of total bilirubin, alkaline phosphatase and GGTP (gamma-glutamyl transferase) and assess the degree of preservation of the main functions of the liver. To exclude the viral nature of liver damage (acute viral hepatitis), which is also accompanied by an increase in ALT and AST in the blood, you will need to donate blood for specific antigens of viral hepatitis and specific antibodies to these antigens.

In some cases, a blood serum test is indicated PCR method for the presence of HBV DNA and HCV RNA.
