Transaminases are an indicator of liver function. If you find elevated transaminases, it means that there is a problem with liver function and you need to go to the hospital for examination and you need to hang up with the gastroenterology department or the department of infectious diseases, and the doctor will ask about your medical history and give you the appropriate tests. If there is a family history of hepatitis B, you need to check the hepatitis B five, HBV-DNA, liver ultrasound and so on. If there is a history of alcohol consumption or obesity, fatty liver needs to be considered, and blood lipid tests, liver ultrasound and liver elasticity tests will be performed. When there is an unexplained elevation of aminotransferases, patients need to undergo virologic tests, including tests for hepatitis A, hepatitis B, hepatitis C, hepatitis D, hepatitis E, or autoimmune antibodies. In some cases, a liver puncture is performed to determine the cause of the elevated transaminases.
