High glutamic transaminase may be hepatitis or other diseases such as fatty liver, cirrhosis and acute myocardial infarction. Glutamine aminotransferase is clinically known as aspartate aminotransferase, abbreviated as AST, with a reference range of 8~40 U/L in normal adults. As a non-specific intracellular functional enzyme, serum glutamine aminotransferase levels are low in the normal population, but when the hepatocytes are damaged, the permeability of the hepatocyte membranes is increased, and serum glutamine aminotransferase indexes will be elevated. Elevated alachlor aminotransferase can be seen in a variety of diseases, such as acute viral hepatitis, chronic viral hepatitis, alcoholic liver disease, drug-induced hepatitis, fatty liver, hepatocellular carcinoma, cirrhosis, intrahepatic cholestasis and other hepatobiliary disorders; it can also be seen in other diseases, such as skeletal muscle disease, pulmonary infarction, renal infarction, shock, and infectious mononucleosis, and so on. High AST may be seen in hepatitis or other diseases, it is recommended to consult a doctor for further diagnosis and treatment to avoid delaying the condition.
