What is the normal range of liver enzymes: High, Low & Normal Results, Symptoms & Causes
Aspartate aminotransferase (AST) blood test Information | Mount Sinai
Aspartate aminotransferase; Serum glutamic-oxaloacetic transaminase; SGOT
The aspartate aminotransferase (AST) blood test measures the level of the enzyme AST in the blood.
Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
How the Test is Performed
A blood sample is needed.
How to Prepare for the Test
No special preparation is needed.
How the Test will Feel
When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away.
Why the Test is Performed
AST is an enzyme found in high levels in the liver, heart, and muscles. It is also found in lesser amounts in other tissues. An enzyme is a protein that causes a specific chemical change in the body.
Injury to the liver results in release of AST into the blood.
This test is mainly done along with other tests (such as ALT, ALP, and bilirubin) to diagnose and monitor liver disease.
The normal range is 8 to 33 U/L.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples. Talk to your health care provider about the meaning of your specific test results.
What Abnormal Results Mean
An increased AST level is often a sign of liver disease. Liver disease is even more likely when the levels of substances checked by other liver blood tests have also increased.
An increased AST level may be due to any of the following:
- Scarring of the liver (cirrhosis)
- Death of liver tissue
- Heart attack
- Too much iron in the body (hemochromatosis)
- Swollen and inflamed liver (hepatitis)
- Lack of blood flow to the liver (liver ischemia)
- Liver cancer or tumor
- Use of drugs that are toxic to the liver, especially alcohol use
- Mononucleosis (“mono”)
- Muscle disease or trauma
- Swollen and inflamed pancreas (pancreatitis)
AST level may also increase after:
- Burns (deep)
- Heart procedures
Pregnancy and exercise may also cause an increased AST level.
There is little risk involved with having your blood taken. Veins vary in size from one person to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.
Risks associated with having blood drawn are slight, but may include:
- Fainting or feeling lightheaded
- Excessive bleeding
- Multiple punctures to locate veins
- Hematoma (blood collecting under the skin)
- Infection (a slight risk any time the skin is broken)

Liver Function Tests | Kaiser Permanente
Some blood tests are used to determine whether your liver is damaged or inflamed. Although these tests help your doctor evaluate how well your liver is working, they cannot tell if you have hepatitis C.
Tests that assess liver function
Your doctor may do tests to measure certain chemicals produced by the liver. These tests can help your doctor check how well your liver is working.
Tests may measure:
- Total serum protein.
Tests that check for inflammation of the liver (liver enzyme studies)
Your liver may be damaged if you have increased levels of:
- Alanine aminotransferase (ALT or SGPT).
- Aspartate aminotransferase (AST or SGOT).
An increased level of alkaline phosphatase (AP) may indicate blockage of bile ducts.
Why It Is Done
Liver tests are done when a medical history or physical exam suggests that something may be wrong with your liver.
These tests can also help diagnose long-term (chronic) infection. If liver enzymes are high, a test for hepatitis C antibodies may be done to see if you have hepatitis C.
If you are being treated with antiviral therapy, you may have liver tests from time to time to see whether treatment is working.
How To Prepare
In general, there’s nothing you have to do before this test, unless your doctor tells you to.
How It Is Done
A health professional uses a needle to take a blood sample, usually from the arm.
All levels are within the normal range.
One or more levels are outside the normal range. Abnormal liver function tests may mean that your liver is inflamed or is not working normally. This can be a sign that you have a viral infection.

Gamma-glutamyltransferase (GGT) – indications, norm, blood test
EN / ENG / UA
The enzyme was first described by Hanes et al. in 1952 GGT – microsomal enzyme involved in amino acid metabolism. Catalyzes the transfer of ?-glutamyl residue from ?-glutamyl peptide to an amino acid or peptide (external transpeptidation), as well as to another substrate molecule (internal transpeptidation). Normally, the specific activity of the enzyme is higher than in blood serum, 7000-7500 times in the kidneys, 600-650 times in the pancreas, 200-500 times in the liver.
Insignificant activity of the enzyme is also recorded in the spleen, intestines, brain, lungs, skeletal muscles, heart, prostate. The enzyme is found in lysosomes, membranes, and cytoplasm of the cell, and membrane localization of GGT is characteristic of cells with high secretory, excretory, or reabsorption capacity. In the blood plasma of newborns, the activity of gamma-glutamyltransferase is 8-10 times higher than in adults, and even more in preterm infants.
During 7-9 months of life, GGT activity in the blood decreases, remaining constant until puberty. The level of the enzyme is also influenced by gender differences. In adolescents from 13 to 17 years old and in adults, the reference values of gamma-glutamyl transpeptidase activity for women are 20-25% lower than for men.
Diagnosis of gamma-glutamyltransferase
Determination of GGT activity in blood serum has become of great importance for the diagnosis of diseases of the liver and hepatobiliary tract, and an increase in serum GGT values is a sensitive indicator in diseases of the hepatobiliary system (marker of cholestasis)
Serum GGT levels increase in all forms of liver disease. The highest activity of the enzyme in cases of obstructive liver damage (5-30 times higher than normal values). This is a more sensitive indicator of liver pathology than ALT and AST in the diagnosis of obstructive jaundice, cholangitis and cholecystitis. The increase in GGT in these cases is observed earlier and lasts longer than other liver enzymes. The activity of gamma-glutamyl tranpeptidases in infectious hepatitis is 2–5 times higher than normal (in these cases, the determination of GGT is less useful than ALT and AST). In almost 100% of cases in cancer patients with liver metastases (without jaundice and with jaundice), a very significant increase in enzyme activity (12 or more times higher than normal) was found. Moreover, changes in activity gamma-glutamyltransferases are observed earlier and are more pronounced than the activities of other enzymes. A slight increase in GGT (2-5 times) is observed in patients with fatty degeneration of the liver.
An increase in enzyme activity is caused by many substances, especially drugs that can induce microsomal oxidizing capacity, as well as any oxidative stress (including diabetic ketoacidosis). After stopping the administration of drugs, GGT activity gradually returns to normal. In patients suffering from acute or chronic pancreatitis, malignant diseases of the pancreas, GGT activity, as a rule, exceeds the norm by 5–15 times.
High GGT activity was noted in the blood of alcoholics. There are certain differences between the activity of GGT in the blood of alcoholics and people who have taken a significant dose of alcohol (in the latter, even after severe intoxication, an increase in activity is observed only for 12 hours and does not exceed 15% of the norm). Therefore, gamma-glutamyltransferase is used to monitor the effectiveness of the treatment of patients with alcoholism. The high specific activity of GGT in the prostate gland, so it can be used as a marker of malignant diseases of the prostate gland. The study of GGT activity in brain lesions has acquired great clinical and diagnostic significance.
Parallel determination of the activity of GGT and alkaline phosphatase (in cases of its increased activity) helps when it is necessary to decide whether their source is an altered bone metabolism or the presence of hepatobiliary disorders, because. in conditions in which alkaline phosphatase is elevated (in healthy pregnant women, in children older than 1 year, in cases of bone diseases), GGT is within normal limits.
Indications for Gamma-glutamyltransferase test
- Diagnosis and differential diagnosis of liver lesions
- Monitoring of the course of pancreatic, prostate, hepatoma cancer
- Screening for alcoholism, monitoring the treatment of people with chronic alcoholism
- Evaluation of hepatotoxicity of drugs
Examination preparation: fasting blood sampling
Examination material: blood serum, avoid hemolysis
Method of determination : kinetic (IFCC)
Units of measure : U/l

Increased gamma-glutamyl transpeptidase values
If you have high GGT, possible reasons for this may be:
- Intra- and extrahepatic cholestasis
- Acute viral hepatitis, toxic, radiation damage to the liver
- Chronic hepatitis
- Acute and chronic pancreatitis
- Alcohol-induced liver injury
- Infectious mononucleosis
- Myotonic dystrophy
- Diabetes mellitus
- Kidney pathology (exacerbations of chronic glomerulo- and pyelonephritis)
- Cancer of the pancreas, prostate, hepatoma
- Taking medications (barbiturates, phenytoin, rifampicin, cephalosporins, estrogens, oral contraceptives, acetaminophen)
The cost of a blood test for the content of gamma-glutamyl transferase
A blood test for the content of gamma-glutamyl transferase costs 35 UAH. It is carried out within 1-2 days. The cost of taking material for research is paid separately (15 – 25 UAH).

Find out which ALT and AST values are normal for women. Useful information about the functions of these indicators and the causes of deviations from the norm.
Alt and Ast are enzymes that are responsible for the functioning of the liver. If their blood levels are elevated, this may indicate a liver problem. A blood test for alt and ast is usually ordered in case of suspected liver disease, but what does a deviation in the level of these enzymes mean in women?
ALT and AST blood levels in women depend on many factors, including age, sex, disease, and medication. But in general, the alt level in women should not exceed 31 units/l, and the ast level should not exceed 34 units/l.
Abnormal alt and ast levels in women may indicate liver problems such as hepatitis, cirrhosis, tumors, and gallstones. However, keep in mind that elevated levels of alt and ast are not always indicative of liver disease. Some medications, such as aspirin, pain pills, and antibiotics, can increase blood levels of these enzymes.
If you have been tested for alt and ast and your blood levels of these enzymes are elevated, be sure to discuss the results with your doctor. He will be able to assess your ALT and AST levels in the context of your health and determine if additional testing or treatment is needed.
ALT and AST – what is it?
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are enzymes found inside liver cells. If liver cells are damaged or destroyed, these enzymes enter the bloodstream. Therefore, an increase in the level of ALT and AST in the blood may indicate the presence of problems with the liver or other organs.
ALT is predominantly present in liver cells, but can also be found in heart cells and other tissues. AST is present in the cells of the liver, heart, muscles and other organs.
ALT and AST are often used together in the diagnosis of liver diseases such as hepatitis and cirrhosis. These enzymes can also be elevated in myocardial infarction, rheumatic diseases, and other problems.
ALT and AST blood test
The blood test for ALT (alianine aminotransferase) and AST (aspartate aminotransferase) is one of the most common methods for diagnosing diseases of the liver and heart. Both are enzymes that are normally found inside the cells of the liver and heart, but if these organs become damaged or inflamed, ALT and AST are released from the cells into the blood, causing their blood levels to rise.
ALT is commonly screened to diagnose liver diseases such as hepatitis, cirrhosis, and liver cancer. ALT levels can also be elevated with certain medications, jaundice, gallbladder disease, and inflammatory diseases of the biliary tract.
AST, on the other hand, can be elevated in a number of conditions, including heart disease, myocardial infarction, liver disease, and muscle disease. AST levels can also be elevated when taking certain medications.
Elevated levels of ALT and AST in the blood may indicate a specific disease, but these indicators cannot indicate a specific condition. To detect the disease, additional research and examinations are necessary.
In general, elevated levels of ALT and AST usually indicate damage to some organs in the body. If you are found to have elevated levels of ALT or AST, you should undergo further tests to find out which organs are damaged and begin treatment under the guidance of a qualified physician.
Normal ALT and AST in women
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are indicators of liver function. Normal blood levels of these enzymes may vary depending on the methodology of the laboratory, as well as the age, sex, and weight of the patient. However, on average, in women, ALT and AST have the following norms:
- ALT: up to 34 units/l;
- AST: up to 31 U/L.
If a woman’s ALT and AST levels are higher than normal, this may indicate liver problems such as inflammation, fatty degeneration, or cirrhosis. However, another underlying cause may also be present, such as alcohol or drug poisoning, drug injection, or heart or muscle disease.
If you have been prescribed ALT and AST tests and find that these levels are abnormal, you should consult your doctor to determine the cause and prescribe the appropriate treatment.
ALT and AST abnormal
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are enzymes that help the body make proteins. Normal levels of ALT and AST in women can vary, but are usually in the range of 7-56 units/L for ALT and 10-40 units/L for AST.
Abnormal levels of ALT and AST may indicate the presence of liver disease such as hepatitis or cirrhosis. If the level remains elevated for a long time, it can lead to serious complications, including liver failure or liver cancer.
ALT and AST levels may also be elevated in other conditions such as myocardial infarction, pneumonia, or myopathies. This can help diagnose these conditions and track their treatment.
If the levels of ALT and AST strongly deviate from the norm, it is recommended to consult a doctor for additional examination and determination of the cause of such deviation. Early detection and treatment of diseases that can lead to elevated levels of ALT and AST can help maintain health and prevent serious complications.
Causes of increased levels of ALT and AST in women
AST (aspartate aminotransferase) and ALT (alanine aminotransferase) are enzymes that are involved in the process of amino acid metabolism. They are found in the cells of the liver, heart muscle, kidneys and other tissues of the body. If the level of ALT and AST is elevated in a woman, this may indicate the presence of the following reasons:
- Liver diseases: elevated levels of ALT and AST may indicate the presence of hepatitis, liver cirrhosis, fatty degeneration and other pathological changes. At the same time, ALT levels may rise earlier than AST.
- Taking medications: Many medications can increase blood levels of ALT and AST. This is especially true of hepatotoxic drugs that have a negative effect on the liver.
- Alcoholic liver disease: The presence of an alcoholic mixture may lead to elevated levels of ALT and AST.
- Myocarditis, cardiac muscle hypoxia: If the heart muscle is affected, AST levels can rise much faster than ALT.
- Non-specific elevation: ALT and AST levels may be elevated with various infectious diseases, trauma and surgery.
In any case, if the level of ALT and AST in a woman is elevated, this requires a mandatory examination and identification of the cause in order to prescribe an effective treatment.
Diseases that cause elevated levels of ALT and AST in women
Elevated levels of ALT and AST may be associated with hepatitis, an inflammation of the liver that can be caused by viruses, alcohol, drugs, and other factors. In hepatitis, ALT and AST are higher than normal due to damage to liver cells and the release of enzymes into the blood.
Cirrhosis of the liver
Cirrhosis of the liver is characterized by the gradual accumulation of damage to the liver cells, which can cause an increase in the level of ALT and AST. With cirrhosis of the liver, the function of the organ is impaired, which can lead to serious consequences.
Obesity can be one of the causes of elevated levels of ALT and AST. Fat accumulates in the liver, which can cause it to malfunction and release enzymes into the blood.
Elevated levels of ALT and AST may also be associated with rarer diseases such as myopathy, muscle wasting, thrombosis, myocardial infarction and others. You need to see a doctor for an accurate diagnosis and treatment.
Symptoms of elevated ALT and AST levels in women
ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes that are found inside the cells of the liver and other organs. Elevated levels of ALT and AST in the blood can indicate problems with the liver, heart, muscles, and other organs.
In women, elevated levels of ALT and AST may present with the following symptoms:0043
If If you notice any of these symptoms, you should see a doctor for diagnosis and treatment. He may order blood tests for ALT and AST levels, as well as other types of tests to identify possible problems with the body.
Do not ignore the symptoms of elevated levels of ALT and AST, as these enzymes can indicate serious diseases that require competent medical attention.
Diagnosis of elevated levels of ALT and AST
A special blood test is performed to determine the level of hormones ALT and AST. This test can help diagnose various diseases of the liver, heart, and muscles.
ALT and AST levels may be elevated in the presence of viral hepatitis, alcoholic or toxic hepatitis, cirrhosis of the liver, infectious mononucleosis, heart and muscle disease. In some cases, an increase in hormone levels may be due to medications taken or tissue damage resulting from an injury.
If the ALT and AST levels are above normal, further investigations are needed to determine the cause of the deviation. Do not panic in advance, because elevated hormone levels do not always indicate a serious illness.
It is important to understand that self-monitoring of ALT and AST levels at home is not sufficient to establish a diagnosis. To do this, you should consult a doctor and perform the recommended tests.
What to do with elevated levels of ALT and AST
If you have been diagnosed with elevated levels of ALT and AST in the blood, do not panic, but do not ignore this fact either. First you need to determine the reason for such a deviation. Usually, elevated levels of ALT and AST indicate complications in the liver.
If elevated ALT and AST levels are caused by a disease or infection, your doctor may prescribe appropriate treatment to address the cause of the increase.
However, sometimes elevated levels of ALT and AST may indicate the presence of chronic diseases of the liver or other organs. In this case, it is necessary to undergo an examination to determine the causes of this condition and prescribe a suitable treatment.
To lower your ALT and AST levels, you need to follow a proper diet, stop bad habits, take the right medications, and have regular medical checkups.
In any case, ALT and AST levels should be monitored regularly. If you find deviations from the norm, you should consult a doctor in a timely manner and undergo an additional examination to find out the causes and prevent possible complications.
Treatment of elevated ALT and AST
As markers of liver damage, ALT and AST are important indicators of liver disease. If ALT and AST levels are high, treatment depends on the underlying cause of the condition.
If elevated levels of ALT and AST are due to alcoholic or viral hepatitis, then the main treatment is the treatment of the underlying disease. In cases of liver failure, increased protein intake and dietary elasticity may be prescribed.
If elevated levels of ALT and AST are associated with medication or supplements, then these drugs should be discontinued. You may have to replace them with safer alternatives.
For people with elevated levels of ALT and AST, it is imperative to control alcohol consumption and the abuse of fatty, rich foods.
Based on the above, you need to understand that elevated levels of ALT and AST require careful consideration and analysis of the causes. Only then can you find the appropriate treatment and make the necessary adjustments in your lifestyle and diet.
Nutrition with elevated ALT and AST levels
Women with elevated ALT and AST levels should pay attention to their diet. Diet can have a big impact on the levels of these enzymes in the blood, so it is recommended to follow certain rules when compiling your daily menu.
What to eat
With elevated ALT and AST levels, a healthy diet is given special attention. Women should eat more fresh fruits and vegetables, as well as protein foods such as fish, chicken, eggs, and cottage cheese. It is also recommended to drink plenty of fluids, including clean water.
What to avoid
Women should limit their intake of fatty and fried foods, as well as sweets and alcohol, to avoid elevated ALT and AST levels. In addition, it is recommended to avoid too much coffee and strong tea.
One way to preserve the health benefits of food is to cook it properly. Women should prefer steamed or grilled dishes. Also, if possible, it is necessary to exclude frying in oil and give preference to cold appetizers and salads.
By following simple healthy dietary guidelines, women can lower their blood levels of ALT and AST. Regular consumption of fresh fruits and vegetables, protein foods, limiting fatty, fried and sugary foods, and proper cooking will help maintain a healthy liver and improve overall body health.
Preventing elevated ALT and AST levels
Maintaining a healthy liver and preventing elevated ALT and AST levels in women requires a healthy lifestyle:
- Avoid alcohol and nicotine;
- Watch your diet and avoid fatty, fried and salty foods;
- Maintain a healthy weight and avoid excess weight;
- Exercise regularly;
- Avoid stress and nervous overload;
- Monitor the level of hormones in the body, especially when taking hormonal drugs.
It is also recommended to undergo regular medical examinations and seek medical attention at the first symptoms of liver disease: pain in the right hypochondrium, nausea, vomiting, jaundice, loss of appetite and drowsiness.
If the level of ALT and AST in the blood of a woman is elevated, then it is necessary to consult a doctor for additional examination and determination of the cause of the deviation.
Sample diet to prevent elevated ALT and ASTV Time Meal
|Breakfast: oatmeal with water, apple, green tea
|Snack: fruit yogurt, nuts
|Lunch: grilled chicken breast, steamed vegetables, slice of rye bread, water
|Dinner: steamed fish, vegetable salad, slice of rye bread, water
ALT and AST levels
Elevated levels of ALT and AST usually indicate liver dysfunction. Such violations can be caused by various reasons: from alcohol or drug intoxication to viral infections or cancer.
One of the first signs of elevated levels of ALT and AST are yellowing eyes and skin, which indicate a violation of the outflow of bile. Other signs may include pain in the right side, bloating, nausea, vomiting, and general weakness.
These signs should not be ignored, as elevated levels of ALT and AST can lead to serious consequences. For example, it can cause cirrhosis of the liver, which in turn can lead to liver cancer and other dangerous diseases. Therefore, if suspicious symptoms appear, you should consult a doctor and undergo an appropriate examination.
- Suspected or developing acute hepatitis
- Confirmed chronic hepatitis
- Suspected gallbladder disease
- May be caused by certain drugs or high alcohol intake
If found elevated high levels of ALT and AST, measures must be taken to eliminate the cause of its occurrence. For this, special medications, diet, avoidance of alcohol and other suitable measures can be prescribed.
Comparison with elevated levels of other blood parameters
The presence of elevated levels of alanine aminotransferase (Alt) and aspartate aminotransferase (AST) can be caused not only by diseases of the liver, cardiovascular system and muscle tissue, but also by the presence of other indicators in the blood, such as iron, glucose, cholesterol and others.
When comparing the levels of Alt and Ast with other indicators, it is necessary to take into account the possible mechanisms for increasing the levels of these enzymes. For example, an increase in the level of Alt and Ast may be associated with a violation of iron metabolism in the body, which leads to its accumulation in the liver and intensive destruction of liver cells.
However, in the presence of elevated levels of Alt and Ast in combination with other indicators, it is necessary to conduct an additional examination to determine the cause of the increase and further treatment.
- Elevated blood glucose may indicate diabetes.
- Elevated cholesterol levels may be associated with impaired lipid metabolism in the body.
- Elevated iron levels may indicate the presence of hemochromatosis.
ALT and AST hepatitis test
Alanine aminotransferase and Aspartate aminotransferase
ALT and AST are enzymes that are found inside liver cells. They are involved in the metabolism of amino acids and help the body get energy from food. High levels of ALT and AST can indicate liver problems, which is why they are usually included in a standard CBC.
One of the most common blood tests for ALT and AST levels is a hepatitis test. Hepatitis is an inflammatory disease of the liver that can be caused by infection, alcohol, or toxins. ALT and AST may be elevated in viral hepatitis, and their rise may reflect the degree of liver damage.
How to prepare for an ALT and AST test
To prepare for an ALT and AST test, you must give blood samples. No other special preparatory measures are required. However, alcohol consumption should be limited prior to testing, as it can increase blood levels of ALT and AST.
What the test results mean
The normal range for ALT and AST blood levels may vary depending on the laboratory that performs the test. Generally, ALT and AST levels should not exceed 30 to 40 units per liter (U/L) in women. If the level of ALT and AST is elevated, then this may indicate a toxic or infectious liver lesion.
If the results of the analysis show high levels of ALT and AST, then it is necessary to consult with the attending physician to identify the possible cause of the elevated ALT and AST levels and begin treatment.
The effect of ALT and AST on pregnancy
ALT and AST are indicators that can be measured in the blood of a pregnant woman at different stages of pregnancy. They play an important role in assessing the health of the liver, but can also indicate problems with the heart and muscles.
Studies show that elevated levels of ALT and AST in the blood of a pregnant woman can indicate the presence of infection, hepatitis, many other diseases, and also negatively affect the development of the child.
Although elevated levels of ALT and AST alone are not dangerous for pregnancy, if both levels are elevated, action must be taken. In this case, the woman should consult a doctor and undergo additional examinations.
In addition, maintaining a healthy lifestyle and proper diet can help reduce the risk of elevated ALT and AST levels. Pregnant women need to pay special attention to their health and monitor the level of these indicators in the blood in order to ensure the health of their child and themselves in general.
When to see a doctor if ALT and AST levels are elevated
If the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in a woman’s blood are elevated, this may be a symptom of various diseases of the liver, cardiovascular system and other organs.
If a woman notices symptoms such as fatigue, nausea, jaundice, right upper quadrant tenderness, she should seek immediate medical attention.
It is also recommended that women undergo regular medical examinations in order to identify possible problems of the disease at an early stage.
To diagnose the level of ALT and AST, it is necessary to donate blood for a biochemical analysis, which can determine the presence of pathological changes.
If ALT and AST levels are elevated, the doctor may order additional tests to determine the cause of the abnormality and prescribe appropriate treatment.
What are Alt and Ast and why are these indicators needed in the analyzes of women?
Alt (alanine aminotransferase) and Ast (aspartate aminotransferase) are enzymes that are found in liver cells and are involved in amino acid metabolism. Their blood levels help diagnose liver disease and assess liver function. When deviating from the norm, Alt and Ast can indicate various pathologies that need to be identified and treated.
What are the normal levels of Alt and Ast in women?
The norm of Alt in women is 10-40 U/l, and the norm of Ast is 10-30 U/l. However, these values may differ depending on the laboratory that performs the analysis. Therefore, when studying the results, it is necessary to be guided by the standards specified in the laboratory where the analyzes were carried out.
What can cause an increase in Alt in women?
An increase in the level of Alt in the blood in women can be caused by diseases such as viral hepatitis, cirrhosis of the liver, fatty liver, as well as the use of alcohol or toxic drugs. Also, an increase in Alt levels may be associated with muscle damage, along with damage to liver cells.

What can it mean if the level of Alt and Ast is simultaneously elevated in women?
Simultaneous elevation of Alt and Ast may indicate various liver diseases such as hepatitis, cirrhosis or cancer. Also, an increase in the level of Alt and Ast may be associated with dysfunction of other organs, such as skin, muscles and pancreas. The final diagnosis can only be made after a comprehensive examination and exclusion of other pathologies.
Can a low level of Ast in women indicate the absence of problems with the liver?
