The normal range value of aminotransferase is usually 0~40U/L. The result of aminotransferase test is 69U/L, which is on the high side. The causes of high transaminase may be physiological reasons, or pathological reasons such as liver disease, heart disease, biliary tract disease. 1. Physiological reasons: such as staying up late, drinking too much alcohol, strenuous exercise, etc. may cause transient elevation of transaminases. 2. Liver disease: such as viral hepatitis, cirrhosis, alcoholic liver disease, drug liver disease, etc., can cause transaminase elevation. 3. Heart disease: such as heart failure, myocarditis, etc. can lead to high aminotransferase. 4. Biliary tract diseases: such as cholecystitis, gallstones, etc., acute attacks can cause high transaminases. It is recommended that patients with high aminotransferases should consult a doctor in time to find out the cause and follow the doctor’s instructions for treatment.
