The normal range for alanine aminotransferase is 0 to 40 U/L, and a result of 46 U/L is higher than normal and is considered abnormal. Alanine aminotransferase is one of the common indicators of liver function tests, which can help doctors diagnose the existence of liver function damage. A numerical result of 46 U/L, which is slightly higher than normal, is needed to clarify the cause of the disease and exclude physiological factors before symptomatic treatment. If the patient is caused by physiological factors such as excessive fatigue, heavy alcohol abuse, mental stress, etc., generally pay more attention to rest, avoid drinking alcohol, more relaxation, most patients can return to normal; if caused by viral hepatitis, cholestasis and other diseases, follow the doctor’s instructions to stop using drugs that damage the liver, take entecavir, silymarin and other drugs for treatment. It is recommended that patients with abnormal alanine aminotransferase results go to the hospital in time to avoid delayed treatment.
