Albuminous aminotransferase 97U/L, suggesting abnormal liver function. Possible causes include viral infection, fatty liver, alcohol injury, drug damage, genetic metabolic liver disease, etc. 1. Viral infection: such as hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, hepatitis E virus, cytomegalovirus, EB virus, which can lead to abnormal liver function. 2. Fatty liver: when liver fat increases, it will cause inflammation, which will also lead to abnormal liver function and make the alanine aminotransferase high. 3. Alcohol damage: the main component of alcohol is ethanol, which can be turned into acetaldehyde and acetic acid through the decomposition of acetaldehyde dehydrogenase, both of which are damaging to the liver, and therefore can also cause liver function abnormalities. 4. Drug damage: drugs can cause liver injury and liver function abnormality, such as acetaminophen. 5. Inherited metabolic liver disease: Inherited metabolic liver disease can also cause liver function abnormality, which is related to own gene. If the situation of elevated glutamyltransferase occurs, you should consult a doctor in time, under the guidance of a professional physician for diagnosis and treatment, and should not deal with it blindly on your own, so as not to cause adverse consequences.
