What is the normal index of transaminase? What is the disease if the transaminase is high? Is it serious?

Checking transaminase is the most common item in the physical examination. It is tested by drawing blood and is mainly used to check liver function. If the transaminase is high, in addition to considering the lifestyle and time of the physical examination before the physical examination, it is also possible that the cause is a disease. So what diseases generally cause high transaminase?

What is the normal index of transaminase?

Normal value: 0~40.

It is generally considered that a level above 40U/L is considered elevated.

Mild elevation: 40-80; moderate elevation: 80-200; severe elevation: > 200. In severe hepatitis, transaminases decrease, but bilirubin and coagulation time are prolonged, and albumin decreases.

Therefore, when we say that the transaminase level is elevated, it generally refers to a mild elevation or the lower part of a moderate elevation.

Is elevated transaminase a serious disease?

Elevated transaminase levels only indicate that the liver may be damaged. In addition to hepatitis, many other diseases can cause elevated transaminase levels.

Common diseases that can cause elevated transaminase levels include:

Diseases of the liver itself, especially various types of viral hepatitis, cirrhosis, liver abscess, liver tuberculosis, liver cancer, fatty liver, hepatolenticular degeneration, etc.;

When myocarditis, pyelonephritis, lobar pneumonia, pulmonary tuberculosis, Japanese encephalitis, polymyositis, acute sepsis, typhoid fever, meningitis, malaria, cholecystitis, leptospirosis, influenza, measles, schistosomiasis, crush syndrome, etc.;

Diseases of the bile duct, gallbladder and pancreas, bile duct obstruction;

Drug-induced or toxic liver damage, as well as drug allergy, can cause elevated transaminases, often accompanied by cholestatic jaundice and hepatocellular damage;

Normal pregnancy, preeclampsia, acute fatty liver of pregnancy, etc.

In addition, the transaminase level of a healthy person may temporarily exceed the normal range, but after a period of time, the transaminase level will return to normal. Because transaminase is very sensitive, the transaminase level of a healthy person may fluctuate at different times of the day. Vigorous exercise, excessive fatigue, or recent consumption of greasy food may cause the transaminase level to be temporarily high.

How to pay attention to diet when transaminase is high

① Eat less food containing chemical additives.

② Eat less high-cholesterol foods, such as seafood, egg yolks, animal offal, and especially shellfish.

③ High transaminase levels indicate liver damage. Avoid drinking alcohol to prevent it from placing more burden on the liver.

④ Eat less or no sashimi and shellfish.

⑤ People with high transaminase levels should avoid eating irritating foods, such as MSG, mustard, chili peppers, and onions.

⑥ People with high transaminase levels should not eat high-fat or high-sugar foods.
