High aminotransferase is an important indicator in liver function test, and high aminotransferase indicates abnormal liver function, mostly due to liver diseases. If the patient has had strenuous exercise, exertion, alcohol consumption, staying up late, fever, etc. before the blood test, it may interfere with the metabolism of the body and cause a mild transient increase in transaminases, which will return to normal after eliminating the above-mentioned adverse factors. If the patient is taking compound aspirin, ibuprofen and other non-steroidal anti-inflammatory drugs, certain antibiotics, anti-epileptic drugs and anti-tuberculosis drugs, which have the side effect of causing elevated aminotransferases due to damage to liver cells, they can gradually recover after stopping the drugs. If the patient is suffering from fatty liver, various types of viral hepatitis, alcoholic liver disease, immune liver disease and other liver diseases can cause liver cell damage, resulting in different degrees of transaminase elevation. In addition, transaminases can be found in various tissues in the body, so diseases such as myocardial infarction, myogenic diseases, hyperthyroidism, and hepatomegaly can also damage body tissues and cause transaminase elevation. In summary, high aminotransferases are not always associated with hepatitis, as many of the diseases mentioned above can cause elevated aminotransferases.
