In liver function tests, if only the alanine aminotransferase is 567 U/L and other items are not high, the condition is not serious; if it is accompanied by increased bilirubin and decreased prothrombin activity, the condition is more serious and dangerous. If there is only an increase in ALT, it may be caused by adverse reactions to certain medications or excessive alcohol consumption. It is recommended to stop the use of drugs that can damage the liver and to stop drinking alcohol under the guidance of a doctor, and to see if the disease recovers on its own. If necessary, liver-protecting and enzyme-lowering medications (e.g. diammonium glycyrrhizinate) can be taken under doctor’s supervision. If the increase in ALT is accompanied by other abnormal test results such as increased bilirubin, the condition is more serious and can be life-threatening. It is recommended to consult a physician to determine the cause of the elevated AAT and to have the condition evaluated by a medical professional, and to follow the doctor’s instructions.
