Liver function tests are normal, but still not feeling well can be checked again for Hepatitis B half-pair test. In the clinic, hepatitis B two-half tests include: hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B E antigen, hepatitis B E antibody and hepatitis B core antibody tests. Liver function in clinical application is mainly liver function biochemical test indexes, including alanine aminotransferase, glutamine aminotransferase, total bilirubin and other indexes, which can check whether there is any damage to the liver and whether there is jaundice. When the liver function test is normal, it does not mean that the liver is completely normal, because some people may be infected with hepatitis B virus, but the body is in the period of immune tolerance, there is no liver damage, if this time to carry out the liver function test, but the results may be within the range of normal values, but there is hepatitis virus in the body, and at the same time, it has a certain degree of contagious. Therefore, even if the liver function is normal, it does not guarantee that there is no problem with the liver, so if necessary, other tests should be conducted.
