The method of checking liver disease needs to rely on blood tests, such as liver function, hepatitis B two-to-half and routine blood tests, and also need to do abdominal ultrasound, CT and other tests to specifically understand the situation. Liver function test is very necessary, mainly to see the condition of liver function, for example, to see whether there is a significant increase in glutamic oxal transaminase, glutamic alanine aminotransferase, if it exceeds the normal value of more than three times or a dozen times, it indicates that the liver is damaged, liver function is impaired. Also check the hepatitis B two half, whether hepatitis B is present, whether it is a major or minor triple positive. Hepatitis B DNA should also be checked, whether there is any replication of the virus or not. It is also necessary to check the abdominal ultrasound to find out whether there is fatty liver, cirrhosis, liver fibrosis or liver tumors, and to find out specifically about the liver disease.
