If the aminotransferase is elevated up to 55 U/L, the elevation is not large. If the aminotransferase is simply elevated and the jaundice index is not elevated, whether treatment is needed depends on what causes it. Some people have mildly elevated aminotransferases after staying up late or having a cold or fever, so they should get more rest and can be taken without medication for the time being, but they should be reviewed regularly. Some people may have been drinking and socializing for a while, so they should stop drinking recently and have their liver function checked regularly in a week, during which time they may not need medication. Some people have elevated transaminases because they are carriers of the hepatitis B virus, and the disease has progressed to cirrhosis, so although the transaminases are not high, the liver is still cirrhotic and should be treated immediately with antiviral therapy. If the elevated transaminases are accompanied by a rise in jaundice indicators, it suggests that liver damage may be more serious, and liver-protective treatment should be given immediately.
