What is the normal range of liver function tests?

If your liver function test results range between 7-56 units/litre for ALT and 10-40 got AST, your liver function is normal. Anything outside the liver function test normal range means there might be some liver problems or liver infection and needs to be diagnosed and treated.

Why is my Alt high?

Liver disease is the most common reason for higher than normal levels of ALT. Very high levels of ALT (more than 10 times normal) are usually due to acute hepatitis, sometimes due to a viral hepatitis infection.

What are normal AST and ALT levels?

What are normal levels of AST and ALT? The normal range of values for AST (SGOT) is about 5 to 40 units per liter of serum (the liquid part of the blood). The normal range of values for ALT (SGPT) is about 7 to 56 units per liter of serum.

What tests show liver function?

What are the most common liver function tests?

  • Alanine transaminase (ALT) test. Alanine transaminase (ALT) is used by your body to metabolize protein.
  • Aspartate aminotransferase (AST) test.
  • Alkaline phosphatase (ALP) test.
  • Albumin test.
  • Bilirubin test.

Can I lower my AST and ALT levels?

People can lower their ALT levels by making lifestyle changes, such as taking regular exercise and changing their diet. Increasing fiber intake, reducing saturated fats and processed foods, as well as consuming a range of nutrients from fruits and vegetables may all help to lower levels.

What does it mean when your AST level is high?

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

Are bananas good for your liver?

Potassium. Low levels may be linked to non-alcoholic fatty liver disease (NAFLD). Fish like cod, salmon, and sardines are good sources. It’s also in veggies including broccoli, peas, and sweet potatoes, and fruits such as bananas, kiwi, and apricots.

Is Alt 30 high?

One recent population study excluded people at risk for NAFLD and concluded that the “healthy range” for serum ALT should be up to 30 U/L for men and 19 U/L for women3.

Which is worse high AST or ALT?

In addition, patients with Wilson’s disease or cirrhosis due to viral hepatitis may have an AST that is greater than the ALT, though the ratio typically is not greater than two. When the AST is higher than ALT, a muscle source of these enzymes should be considered….

AST/ALT ratio
LOINC 16325-3, 1916-6

How is abnormal liver function treated?

Treatment for liver disease depends on your diagnosis. Some liver problems can be treated with lifestyle modifications, such as stopping alcohol use or losing weight, typically as part of a medical program that includes careful monitoring of liver function.

When should I worry about AST and ALT?

An AST/ALT ratio higher than one (where the AST is higher than ALT) is suggestive of cirrhosis. An AST/ALT ratio higher than 2:1 (where the AST is more than twice as high as the ALT) is suggestive of alcoholic liver disease.

What happens if Alt is high?

High levels of ALT may indicate liver damage from hepatitis, infection, cirrhosis, liver cancer, or other liver diseases. Other factors, including medicines, can affect your results. Be sure to tell your health care provider about all the prescription and over-the counter medicines you are taking.

What is the upper limit of normal for ALT?

The upper limit of normal (ULN) for serum alanine aminotransferase (ALT) has long been used as 40 IU/L. However, this value was determined before the introduction of anti-HCV testing and establishment of the concept of nonalcoholic fatty liver disease (NAFLD).

Do routine blood tests show liver problems?

Blood tests used to assess the liver are known as liver function tests. But liver function tests can be normal at many stages of liver disease. Blood tests can also detect if you have low levels of certain substances, such as a protein called serum albumin, which is made by the liver.

What is a normal ALT level for a woman?

The normal value for ALT in blood ranges from 29 to 33 units per liter (IU/L) for males and 19 to 25 IU/L for females, but this value can vary depending on the hospital. This range can be affected by certain factors, including gender and age.

What is the ALT level for cirrhosis?

In patients with chronic viral hepatitis B or C, cirrhosis has been demonstrated in those with a normal ALT, which limits its use as a diagnostic tool. The main use of ALT in viral hepatitis is therefore in the monitoring of anti-viral treatment. Again, an AST:ALT ratio >1 suggests cirrhosis.

What blood tests indicate liver disease?

Some common liver function tests include:

  • Alanine transaminase (ALT).
  • Aspartate transaminase (AST).
  • Alkaline phosphatase (ALP).
  • Albumin and total protein.
  • Bilirubin.
  • Gamma-glutamyltransferase (GGT).
  • L-lactate dehydrogenase (LD).
  • Prothrombin time (PT).

What AST and ALT levels indicate liver disease?

The AST is typically in the 100 to 200 IU/L range, even in severe disease, and the ALT level may be normal, even in severe cases. The AST level is higher than the ALT level, and the ratio is greater than 2:1 in 70% of patients. A ratio greater than 3 is strongly indicative of alcoholic hepatitis.

What are the first signs of a bad liver?

Symptoms

  • Skin and eyes that appear yellowish (jaundice)
  • Abdominal pain and swelling.
  • Swelling in the legs and ankles.
  • Itchy skin.
  • Dark urine color.
  • Pale stool color.
  • Chronic fatigue.
  • Nausea or vomiting.

What does it mean when your liver test is abnormal?

Your liver tests can be abnormal because: Your liver is inflamed (for example, by infection, toxic substances like alcohol and some medicines, or by an immune condition). Your liver cells have been damaged (for example, by toxic substances, such as alcohol, paracetamol, poisons).

Can abnormal liver function be reversed?

Cirrhosis. Cirrhosis is a stage of ARLD where the liver has become significantly scarred. Even at this stage, there may not be any obvious symptoms. It’s generally not reversible, but stopping drinking alcohol immediately can prevent further damage and significantly increase your life expectancy.
