An alanine aminotransferase of 37 high U/L is not high and is within the normal range of values. Albumin transaminase is generally found mostly in the tissue cells of the liver and heart, and may be elevated when the cells in the tissues are diseased. Clinically, the normal value of alanine aminotransferase is usually between 0 and 40 U/L, and the range of normal values may vary due to the instruments and reagents used in the test. Abnormal elevation is diagnosed when the alanine aminotransferase exceeds 2.5 times the upper limit of the normal reference value and is accompanied by persistent abnormalities. It is recommended to identify the cause of the abnormally elevated ALT, and then follow the doctor’s instructions to treat the cause of the abnormally elevated ALT. During the treatment period, liver function should be checked regularly and the treatment program should be adjusted according to the results.
