In general, transaminases over 200 can rarely be reduced to 15 on their own, and even if they exist, there is a possibility of relapse if the cause is not identified. Therefore, once the aminotransferases are elevated to more than 200, it is recommended to visit the liver disease center of a specialized hospital in a timely manner, so that the cause of the disease can be clarified by the doctor and the cause can be removed before it can be reduced to normal. The standard for aminotransferase test is 40U/L. When the aminotransferase is 200U/L, it means that the aminotransferase has exceeded 5 times the normal value, and generally speaking, exceeding 2 times the normal value means that the liver has been damaged. The cause can be either drug-related or pathological. If the aminotransferases are elevated due to drug-related factors, they can return to normal within 2-3 days after stopping the drug. If the aminotransferases are elevated due to other pathological factors, such as fatty liver, the problem of fatty liver should be solved; if it is caused by virus, antiviral treatment and corresponding liver-protective and enzyme-lowering treatment should be administered to bring it down to normal. In addition, it is important to note that transaminases are considered normal when they are reduced to 40 U/L.
