The five hepatitis B tests are commonly done in the laboratory regarding hepatitis B. They include hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B E antigen, hepatitis B E antibody and hepatitis B core antibody. Generally speaking, a positive second and fifth item means that the previous HBV infection has cleared and the virus is protective. At this time it is usually recommended to check the quantification of hepatitis B virus, which can be done with ultrasensitive hepatitis B virus quantification to check whether there is a certain amount of virus remaining in the body, i.e. the possibility of occult hepatitis B, and if it exists it should be treated actively. At the same time, it is recommended that family members also be checked for hepatitis B five to see if they have potential infection. If the hepatitis B five items 2 and 5 are positive, you should pay attention to improving your living habits, get more rest, avoid straining, try not to smoke or drink, and do not take medication on your own, do physical exercise properly, and eat more low-fat and high-protein food.
