What is an AST Blood Test and Why is it Important?

An AST (aspartate aminotransferase) blood test is a crucial diagnostic tool used to assess liver health and function. AST is an enzyme primarily found in the liver, but it’s also present in muscles and other organs throughout the body. When cells containing AST are damaged, the enzyme is released into the bloodstream. By measuring AST levels in the blood, healthcare providers can gain valuable insights into potential liver damage or disease.

The importance of the AST test lies in its ability to:

• Detect early signs of liver damage
• Monitor the progression of liver diseases
• Evaluate the effectiveness of treatments for liver conditions
• Screen for liver problems in high-risk individuals

Common Uses of the AST Test

Healthcare providers often order AST tests as part of routine blood screenings or when liver problems are suspected. The test may be used to:

1. Diagnose liver diseases such as hepatitis or cirrhosis
2. Monitor liver function in patients with known liver conditions
3. Assess the severity of liver damage
4. Evaluate the effects of medications that may impact liver function
5. Screen for liver problems in individuals with risk factors

Understanding AST Levels and Their Significance

AST levels in the blood can provide valuable information about liver health. But what exactly do these numbers mean? Normal AST levels typically range from 10 to 40 units per liter (U/L), although this can vary slightly depending on the laboratory and testing method used.

Elevated AST levels may indicate:

• Acute or chronic liver disease
• Hepatitis (viral or alcoholic)
• Cirrhosis
• Mononucleosis
• Heart problems
• Pancreatitis
• Muscle damage or injury

Can AST levels fluctuate? Yes, AST levels can fluctuate due to various factors, including:

• Recent strenuous exercise
• Certain medications
• Alcohol consumption
• Diet
• Time of day

It’s important to note that a single elevated AST result doesn’t necessarily indicate a serious liver problem. Your healthcare provider will consider your overall health, symptoms, and other test results when interpreting AST levels.

The AST Testing Process: What to Expect

If your healthcare provider orders an AST test, you may wonder what the process entails. The test itself is relatively simple and straightforward:

1. A healthcare professional will clean an area on your arm with an antiseptic.

2. They will insert a small needle into a vein to draw a blood sample.

3. The blood is collected in a vial or test tube.

4. The needle is removed, and the puncture site is covered with a bandage.

5. The blood sample is sent to a laboratory for analysis.

Is the AST test painful? While you may feel a slight sting when the needle is inserted or removed, the discomfort is usually minimal and short-lived. Some people may experience minor bruising at the puncture site, but this typically resolves within a few days.

Preparing for Your AST Test

In most cases, no special preparation is required for an AST test. However, since AST tests are often ordered alongside other blood tests, your healthcare provider may ask you to fast for up to 12 hours before the test. It’s essential to follow any specific instructions provided by your healthcare team to ensure accurate results.

Interpreting AST Test Results: What Do They Mean?

Receiving your AST test results can be confusing without proper context. While elevated AST levels often indicate liver problems, it’s crucial to understand that other factors can influence the results. Your healthcare provider will consider various aspects when interpreting your AST test, including:

• Your overall health and medical history
• Any symptoms you’re experiencing
• Results from other liver function tests
• Recent alcohol consumption or medication use
• Your age, sex, and physical activity level

How much do AST levels need to be elevated to indicate a problem? While minor elevations may not be cause for immediate concern, AST levels more than 10 times the upper limit of normal often suggest significant liver damage. However, it’s essential to remember that AST levels alone don’t provide a complete picture of liver health.

The Relationship Between AST and ALT

Healthcare providers often order an ALT (alanine transaminase) test alongside the AST test. ALT is another liver enzyme that can provide additional insights into liver function. The ratio of AST to ALT can help differentiate between various liver conditions:

• An AST/ALT ratio greater than 2:1 may suggest alcoholic liver disease
• An AST/ALT ratio less than 1:1 is more common in viral hepatitis
• Equal elevations in both AST and ALT may indicate other forms of liver damage

Risk Factors and Indications for AST Testing

While AST tests can be part of routine health screenings, certain factors may increase the likelihood of needing this test. Healthcare providers may recommend AST testing for individuals with:

• A family history of liver disease
• Alcohol use disorder
• Obesity
• Diabetes
• Exposure to hepatitis viruses
• Use of medications known to affect liver function

Additionally, AST tests may be ordered if you’re experiencing symptoms that could indicate liver problems, such as:

• Jaundice (yellowing of the skin and eyes)
• Abdominal pain or swelling
• Nausea and vomiting
• Fatigue and weakness
• Loss of appetite
• Dark urine or light-colored stools
• Persistent itching

Should you request an AST test if you have these risk factors or symptoms? It’s always best to consult with your healthcare provider. They can assess your individual situation and determine whether an AST test or other liver function tests are necessary.

Beyond AST: Other Liver Function Tests

While the AST test provides valuable information about liver health, it’s often just one piece of the puzzle. Healthcare providers frequently order AST tests as part of a comprehensive liver function panel. This panel may include:

• ALT (alanine transaminase)
• ALP (alkaline phosphatase)
• GGT (gamma-glutamyl transferase)
• Bilirubin
• Albumin
• Prothrombin time

How do these tests complement the AST test? Each of these tests provides unique insights into different aspects of liver function. For example:

• ALT is more specific to liver damage than AST
• ALP can indicate bile duct obstruction
• GGT is sensitive to alcohol use and certain medications
• Bilirubin levels can help diagnose conditions like jaundice
• Albumin and prothrombin time reflect the liver’s ability to synthesize proteins

By combining these tests, healthcare providers can gain a more comprehensive understanding of liver health and function.

Managing Elevated AST Levels: Lifestyle Changes and Treatment Options

If your AST test results show elevated levels, your healthcare provider may recommend various strategies to improve liver health and address underlying causes. These may include:

Lifestyle Modifications

• Limiting or avoiding alcohol consumption
• Maintaining a healthy weight through diet and exercise
• Managing diabetes and other chronic conditions
• Avoiding exposure to toxins and chemicals that can damage the liver

Dietary Changes

A liver-friendly diet may include:

• Increasing intake of fruits, vegetables, and whole grains
• Reducing consumption of saturated fats and processed foods
• Limiting salt intake
• Staying hydrated with water and other non-alcoholic beverages

Medical Treatments

Depending on the underlying cause of elevated AST levels, your healthcare provider may recommend:

• Antiviral medications for viral hepatitis
• Medications to manage autoimmune liver diseases
• Treatment for alcohol use disorder
• Management of other conditions affecting liver function

Can elevated AST levels be reversed? In many cases, yes. With appropriate lifestyle changes and medical interventions, AST levels can often be brought back to normal ranges. However, the success of treatment depends on the underlying cause and the extent of liver damage.

The Future of Liver Health Assessment: Emerging Technologies and Approaches

While AST and other traditional liver function tests remain valuable tools, researchers are continuously exploring new ways to assess liver health more accurately and non-invasively. Some promising developments include:

Advanced Imaging Techniques

• Elastography: Uses sound waves to measure liver stiffness, indicating fibrosis or cirrhosis
• Magnetic Resonance Imaging (MRI): Provides detailed images of liver structure and can detect fat accumulation
• Contrast-Enhanced Ultrasound: Helps visualize liver blood flow and detect tumors

Novel Biomarkers

Researchers are investigating new blood-based markers that may offer more specific and sensitive indicators of liver health, such as:

• Cytokeratin-18 fragments
• microRNAs
• Enhanced Liver Fibrosis (ELF) score

Genetic Testing

Advances in genetic testing may help identify individuals at higher risk for certain liver diseases, allowing for earlier intervention and personalized treatment approaches.

How might these developments impact liver health assessment in the future? As these technologies continue to evolve and become more widely available, they may complement or even replace some traditional liver function tests. This could lead to earlier detection of liver problems, more accurate diagnoses, and more targeted treatment strategies.

In conclusion, the AST blood test remains a crucial tool in assessing liver health and function. By understanding the significance of AST levels, the testing process, and the broader context of liver function assessment, individuals can take a more active role in maintaining their liver health. As medical science advances, we can look forward to even more precise and comprehensive methods of evaluating liver function, ultimately leading to better outcomes for those affected by liver diseases.

AST Test: MedlinePlus Medical Test

What is an AST Test?

AST (aspartate aminotransferase) is an enzyme that is found mostly in the liver, but it’s also in muscles and other organs in your body. When cells that contain AST are damaged, they release the AST into your blood. An AST blood test measures the amount of AST in your blood. The test is commonly used to help diagnose liver damage or disease.

Other names: SGOT test, serum glutamic oxaloacetic transaminase test; aspartate transaminase test

What is it used for?

An AST blood test is often part of a routine blood screening to check the health of your liver. The test may help diagnose or monitor liver problems. It may also help diagnose other health conditions.

Why do I need an AST blood test?

You may get an AST blood test as part of your routine checkup or if you have symptoms of liver damage. These may include:

• Nausea and vomiting
• Lack of appetite
• Fatigue
• Weakness
• Jaundice, a condition that causes your skin and eyes to turn yellow
• Swelling and/or pain in your abdomen (belly)
• Swelling in your ankles and legs
• Dark-colored urine (pee) and/or light-colored stool (poop)
• Frequent itching

Even if you don’t have symptoms, your health care provider may order an AST blood test if you’re more likely to develop liver disease because of:

• A family history of liver disease
• Alcohol use disorder
• Obesity
• Diabetes
• Taking certain medicines that can cause liver damage
• Hepatitis or exposure to hepatitis

What happens during an AST blood test?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for an AST blood test. But an AST test is usually ordered with other blood tests. You usually need to fast (not eat or drink) for up to 12 hours before these tests. Your provider will let you know if there are any special instructions to follow.

Are there any risks to the test?

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

What do the results mean?

High levels of AST in the blood may be a sign of hepatitis, cirrhosis, mononucleosis, or other liver diseases. High AST levels may also be a sign of heart problems or pancreatitis.

If your results are not in the normal range, it doesn’t always mean that you have a medical condition that needs treatment. Many things can affect your results, such as certain medicines and your age, sex, and diet. To learn what your results mean, talk with your provider.

Learn more about laboratory tests, reference ranges, and understanding results.

Is there anything else I need to know about an AST blood test?

Your health care provider may order an ALT blood test with your AST blood test. ALT stands for alanine transaminase, which is another type of liver enzyme. If you have high levels of AST and/or ALT, it may mean that you have some type of liver damage.

You may also have an AST test as part of a group of liver function tests that measure ALT, and other enzymes, proteins, and substances in the liver.

What To Do About Fluctuating Liver Enzyme Levels

Liver enzymes are proteins the liver produces. The amount of these proteins in your blood is a good indication of your liver’s overall health. But elevated liver enzyme levels do not always mean serious liver damage or disease.

Sometimes, factors such as hormonal changes or reactions to medications can cause temporarily elevated liver enzyme levels. Elevated levels caused by these factors will generally return to normal in about 2 to 4 weeks without treatment.

Your liver makes proteins called liver enzymes that help your body perform necessary functions. For instance, liver enzymes help your body:

• fight infections
• make coagulation proteins that are necessary for blood clotting
• break down the food you eat
• break down toxins

Your liver makes several liver enzymes, including:

• Aspartate transaminase (AST)
• Alkaline phosphatase (ALP)
• Alanine transaminase (ALT)
• Gamma-glutamyl transferase (GGT)

These liver enzyme levels are a good indicator of how well your liver is functioning. A liver panel test checks liver enzyme levels in your blood.

A healthcare professional might order this test as part of routine blood work, as a way to monitor you if you’re at risk for liver disease, or as a diagnostic test if you have symptoms of liver disease or liver damage.

There are many reasons liver enzyme levels can change. Some causes are temporary and will resolve on their own. Other causes are more serious and will require medical treatment.

Temporary causes of changes in liver enzyme levels include:

• Hormones: Fluctuations in your liver levels can occur during your menstrual cycle and pregnancy.
• Certain medications: Some medications, including acetaminophen, antibiotics, and some cholesterol-lowering medications, can elevate your liver enzyme levels.
• Herbal supplements: Supplements such as iron, vitamin A, comfrey, and chaparral can elevate liver enzyme levels.
• Alcohol: Heavy drinking can raise your liver enzyme levels.

Causes of elevated liver enzyme levels that are more likely to be chronic include:

• Fatty liver disease: Heavy alcohol use, obesity, and a range of other factors can cause fatty liver disease. No matter the cause, fatty liver disease raises your liver enzyme levels.
• Hemochromatosis: Hemochromatosis is a rare condition that occurs when your body builds up too much iron. Elevated liver enzyme levels can be a symptom of the condition.
• All types of hepatitis: Any type of hepatitis, including hepatitis A, hepatitis B, hepatitis C, autoimmune hepatitis, and alcoholic hepatitis, causes liver inflammation and elevated liver enzymes.
• Cirrhosis: Cirrhosis is chronic liver damage. This damage causes elevated levels of liver enzymes.
• Liver cancer: Cancer that impacts your liver will also affect your liver enzyme levels.
• Hemolysis: Hemolysis is a type of anemia that occurs when your red blood cells are destroyed. It’s sometimes seen with alcohol-related liver diseases, and it can cause changes to liver enzyme levels.
• Thyroid disease: Hyperthyroidism can sometimes cause high levels of liver enzymes.
• Metabolic syndrome: Metabolic syndrome is a term that refers to a group of conditions that raise your risk of diabetes, heart disease, and stroke. These conditions include high blood pressure, high cholesterol, high blood sugar, and carrying excess weight around your midsection. People with metabolic syndrome may also have elevated liver levels.

The exact threshold for what is considered an elevated level or a typical level depends on your age, gender, health goals, and the values used by the specific lab. You can see some standard thresholds below.

• AST: under 36 U/L
• ALP: between 20 and 140 U/L
• ALT: under 25 U/L for women or under 33 U/L for men
• GGT: between 5 and 40 U/L

A liver function test might also measure:

• Albumin: between 35 and 50 U/L
• Bilirubin: between 0. 1 and 1.2 mg/dl

These values are not enzymes, but they’re also important chemicals made by your liver.

A liver function test is a standard blood draw. It can be done during a regular office visit. You don’t generally need any special preparation before a liver function test, although a doctor might ask you to fast for 12 to 24 hours before the blood draw. You can read more about liver function tests here.

The treatment for elevated liver enzymes depends on the cause. In many cases, liver enzyme levels return to normal on their own within about a month. You might need to switch medications, stop taking a supplement, or cut back on drinking if you drink, but you will not need a treatment plan.

In other cases, your doctor might need to treat the condition that’s raising your liver enzyme levels. They might order more tests, such as imaging tests, to get a better look at your liver or blood tests. They might also order a liver biopsy. Depending on your results, you might be referred to a specialist. Treatment will depend on your final diagnosis.

If you’re concerned your liver enzyme levels might be elevated, you might consider making some lifestyle changes at home, such as:

• reducing or eliminating alcohol from your diet
• being cautious about the medications and supplements you take
• staying active, including exercising regularly
• trying to add liver-friendly foods to your diet
• maintaining a moderate weight

Liver enzyme levels are an important indication of your liver’s health. When your enzyme levels are too high, it can be a symptom of liver damage or disease.

Some causes of elevated liver levels, such as hormonal changes or certain medications, are temporary and might resolve without treatment. Other causes are more serious and can include conditions such as cirrhosis, hepatitis C, and liver cancer.

Treatment for high liver enzyme levels depends on the cause.

Find out what the norm of alt and ast means in a blood test for women. Which values ​​are normal, and which may indicate diseases. The importance of timely and correct decoding of a blood test for maintaining health.

The results of a biochemical blood test are one of the key indicators of the health of the body. It is especially important to correctly interpret the level of AST (aspartate aminotransferase) and ALT (alanine aminotransferase), as they are a reflection of the work of the liver. Blood tests for AST and ALT are often prescribed in combination with other indicators to assess liver function, determine the nature of the disease and monitor the progress of treatment.

For women, normal levels of AST and ALT may differ slightly from those for men, in addition, during pregnancy and some other conditions, there may be significant changes in enzyme levels. Therefore, it is important to know the features of the interpretation of the results and the possible causes of deviations from the norm.

In this article we will tell you what are the norms of the levels of AST and ALT in the blood in women, what means their increase or decrease, as well as what factors can affect the result of the tests. If you find deviations from the norm, do not panic, perhaps this is a temporary phenomenon, but additional consultation with a doctor and diagnosis of the condition of the liver is necessary.

Blood test norm for women: ALT and AST

ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes that are found in the cells of the liver, heart, muscles and other tissues of the body. Their level in the blood can be increased in diseases of these organs, as well as in other pathologies.

The norm of AST in women is from 7 to 31 units per liter of blood. An increase in AST levels can be associated with diseases of the liver, cardiovascular system, as well as muscle injuries.

It is important to remember that ALT and AST limits may differ depending on the laboratory where the blood was tested. Therefore, the doctor should interpret the results, taking into account all the factors affecting the level of these enzymes.

What is a blood test?

A blood test is a laboratory study of a biological fluid that circulates through a person’s blood vessels. This analysis is one of the most common methods for diagnosing many diseases, as well as monitoring the state of the body, both in case of deterioration and improvement of its health.

A blood test goes through many stages, from taking blood to interpreting the results. When conducting an analysis, various factors should be taken into account, such as age, gender, physical condition, the presence of chronic diseases and the use of drugs.

Various blood tests, such as hemoglobin, leukocytes, platelets, ALT, AST and many others, may indicate various diseases or abnormalities in the body.

What do ALT and AST mean?

ALT and AST are enzymes found in liver cells. ALT (alanine aminotransferase) and AST (aspartate aminotransferase) can be used as indicators of liver damage. These enzymes are released from liver cells into the bloodstream when an organ is damaged or diseased, and their levels can indicate how severe the damage is.

High levels of ALT and AST in the blood of women may indicate the presence of liver disease or other diseases such as hepatitis, cirrhosis or liver tumors. However, elevated levels of ALT and AST may also be indicative of other non-liver related conditions, such as heart failure.

Why is it important to know the norms of ALT and AST?

Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) are enzymes found in liver and heart cells. If their level in the blood is elevated, this may indicate damage to the cells of these organs.

Measurement of ALT and AST levels in the blood is an important blood test that provides information about the state of the liver and heart in women. Elevated levels of ALT and AST may indicate various diseases, such as hepatitis, cirrhosis, heart failure, and others.

ALT and AST values ​​are indicative and may vary depending on the woman’s age, sex and lifestyle. Therefore, it is important to know the norm of ALT and AST for women in order to make it easier to determine the presence of any diseases.

If ALT and AST are elevated, see a doctor who can diagnose and suggest treatment. Treatment may be aimed at eliminating the causes of increased enzyme levels, as well as restoring liver and heart function.

How is ALT and AST analyzed?

The ALT and AST test is a common blood test. Usually, blood is taken from a vein in the elbow for analysis. Before passing the analysis, you must follow the rules of preparation.

After the blood has been collected, it is sent to a laboratory where it is analyzed for ALT and AST levels. The results of the analysis are usually ready in a few days.

When analyzing ALT and AST, be aware that the results may vary depending on age, sex, physical activity and the use of certain medications. Therefore, before the analysis, it is necessary to consult a doctor and follow the recommendations for preparation.

How to prepare for ALT and AST analysis?

ALT and AST analysis requires some preparation in order for the results to be accurate and reliable. Here are some tips to help you properly prepare for this analysis.

• Refusal of food 8-12 hours before the test. It is best to take the test in the morning on an empty stomach so as not to affect the results. This means that 8-12 hours before blood collection, you need to refuse food.
• Medication withdrawal. Be sure to tell your doctor if you are taking any medications. Some medicines may interfere with the results of the test. If your doctor thinks you need to stop taking your medication, it’s best to follow their advice.
• Refusal of alcohol one day before the analysis. Alcohol can interfere with test results, so alcohol should be avoided the day before the test.
• Maintaining rest and avoiding exercise. Physical activity can also affect the results of the test, so the day before it is taken, physical activity should be avoided and rest should be observed.
• Blood collection compliance. To obtain accurate and reliable results, you must follow the rules for collecting blood. The blood collection process itself should not take more than 5-7 minutes and take place in a sterile environment.

By following these guidelines, you can be confident that your ALT and AST results will be reliable and will help your doctor make the right diagnosis and treatment.

The norm of ALT and AST in women: age characteristics

ALT and AST are important indicators of the functional state of the liver, determined in the blood.

It is possible to establish the norm of ALT and AST in the blood of women only taking into account age characteristics.

So, for example, in women under the age of 50, the ALT norm is up to 31 units per liter of blood, and in women over 50 years old – up to 35 units.

The norm of AST for women under the age of 50 is up to 31 units per liter of blood, after 50 years – up to 35 units.

It should also be noted that during pregnancy, women may experience changes in ALT and AST levels, which usually return to normal after childbirth.

In any case, if you find abnormalities in ALT and AST, you should contact a specialist for further diagnosis and treatment.

What diseases can affect the blood levels of ALT and AST in women?

Blood levels of ALT and AST in women can increase as a result of various diseases. For example, hepatitis is one of the main causes of elevated levels of ALT and AST. This is due to the fact that these enzymes are found in high concentration in the liver, and in hepatitis, the liver tissue can be damaged, which leads to the release of large amounts of ALT and AST into the blood.

In addition, diseases that affect the biliary tract, such as gallstones and cholangitis, can also increase ALT and AST levels. The levels of these enzymes may also increase in women with cardiovascular disease such as myocardial infarction or arrhythmia.

1. Hepatitis;
2. Cirrhosis of the liver;
3. Oncological diseases;
4. Muscular diseases;
5. Gallstone disease;
6. Cholangitis;
7. Cardiovascular diseases;

What if ALT and AST levels are high?

If ALT and AST levels are elevated in a woman’s blood test, a doctor should be consulted for diagnosis and possible causes. Perhaps an increase in the level of these indicators may indicate diseases of the liver or other organs.

Your doctor may order additional tests, such as an ultrasound of the liver, a CT scan, or a liver biopsy, for diagnosis. In addition, it is necessary to analyze urine and blood for the presence of infections, viruses and other pathological processes.

If the reason for the increase in ALT and AST levels is related to the disease, it is necessary to undergo treatment prescribed by a doctor. This may include medication, diet, and other measures, depending on the specific disease and its stage.

In addition, women who have high ALT and AST levels should lead a healthy lifestyle, give up addictions and watch their diet. It is recommended to increase the amount of vegetables and fruits consumed, reduce the intake of fatty and fried foods, and also pay attention to the quantitative and qualitative composition of food.

• see a doctor for diagnosis;
• complete the required tests;
• get treated by a doctor;
• lead a healthy lifestyle and watch your diet.

What factors can increase blood levels of ALT and AST?

Preparations. In addition to drugs that fight liver disease, many drugs can increase blood levels of ALT and AST, such as antiviral drugs, anabolic steroids, anticancer drugs, and others.

Alcohol. Regular alcohol consumption can lead to liver damage and possible increase in blood levels of ALT and AST.

Wrong diet. Excessive consumption of fatty and fried foods can lead to impaired liver function and increased levels of ALT and AST in the blood.

Inflammatory diseases of the liver. Viral, alcoholic or autoimmune hepatitis, cirrhosis of the liver, fatty degeneration cause liver inflammation, which increases the level of ALT and AST in the blood.

Examples of drugs that can increase ALT and AST in the blood Drug Group

Can I decode the results of ALT and AST analysis myself?

Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) are enzymes that are found in liver cells without penetrating into the blood. They are released into the blood only under pathological conditions of the organ. Changes in the levels of these enzymes indicate damage to liver and/or heart cells.

Decoding of ALT and AST results may only be performed by qualified medical personnel after examining the patient and performing other investigations.

Although regular analysis of ALT and AST levels helps to identify possible diseases in the very early stages, you should not try to diagnose yourself. The best solution is to consult with your doctor.

A biochemical blood test is considered one of the main ways to find out if the liver copes with the load of “wrong” nutrition, alcohol, and medication. This will be told by such indicators in the analysis as ALT (alanine aminotransferase) and AST (aspartate aminotransferase) – these liver enzymes are among the first to respond to malfunctions of the organ.

– If there is an increase in both ALT and AST, this means that the liver cells are destroyed and the enzymes from them enter the blood. (…) An increase in AST and ALT means that an inflammatory process is taking place in the liver and its cells are being destroyed. If the indicators are above the norm, you need to contact a gastroenterologist, – gastroenterologist Maria Lopatina wrote in her telegram channel, adding that the upper limits of the norm may differ in different laboratories and one must focus on those established where the analysis was taken.

The doctor named the 4 most common causes of increased liver values.

Chronic viral hepatitis

With an increase in ALT and AST in the blood, viral hepatitis B and C are always excluded first. This is very important, as they can be asymptomatic, while destroying the liver. Mandatory tests: HBsAg – hepatitis B and Anti-HCV – hepatitis C.

Non-alcoholic fatty liver disease

When fatty degeneration of liver cells destroys them, ALT and AST increase in the blood and steatohepatitis develops.

Fatty liver disease is suspected if:

• Waist circumference ≥94/≥80 cm in men/women;

• Blood pressure 130/85 mmHg And more, or the person is taking antihypertensive drugs;

• Fasting glucose level of 5.6 mmol/l or more, or the person is taking hypoglycemic drugs;

• Serum triglycerides more than 1.7 mmol/l;

• High-density lipoprotein (HDL) level less than 1.0/1.3 mmol/l in men/women.

Drug-induced liver injury

All drugs that we take by mouth pass through the liver. The more drugs we take, the more likely it is to be damaged. This group includes both herbal preparations and dietary supplements. Liver damage can occur immediately or after several weeks.

Alcohol

According to Russian clinical guidelines, a safe dose for the liver in women is 20 grams of ethanol per day, for men – 40 grams. Regular excess of this dose leads to the development of alcoholic hepatitis and an increase in ALT and AST.

Determining the ethanol content in 100 ml of a drink is very simple: the percentage of alcohol in the drink must be multiplied by 0.8. Thus, 100 ml of 40% vodka contains 40×0.8=32 grams of ethanol, and 100 ml of 12% wine contains 12×0.8=9.6 grams of ethanol.

The doctor explains that there are other reasons for the increase in ALT and AST in the blood, but these four are the most common.

When an increase in the indicator is not a cause for alarm

It happens that an increase in the level of “liver” indicators may not be associated with a problem in the work of our main “filter”. According to gastroenterologist Maria Lopatina, this may be the case if only the AST index is elevated.

– AST is found not only in the liver, but also in the heart, muscles, kidneys, brain and pancreas. If AST levels are elevated and ALT is normal, causes that are not related to damage to liver cells should be ruled out. For example, active training for all muscle groups, the doctor clarifies.

But if the liver values ​​are below normal in the blood test, in most cases this is not a cause for serious concern. According to the gastroenterologist, a decrease in their level can occur during pregnancy, starvation and a reduced content of vitamin B6.
