Hepatitis B is also known as hepatitis B two-and-a-half, including hepatitis B surface antigen (HBSAg), hepatitis B surface antibody (HBSAb / anti-HBs), e antigen (HBeAg), e antibody (HBeAb / anti-HBe), core antibody (HBcAb / Anti-HBc). Five tests for hepatitis B are to take out the patient's venous blood and test the serological markers of hepatitis B virus in the blood.

Hepatitis B five antigens include hepatitis B surface antigen, hepatitis B surface antibody, e antigen, e antibody, and core antibody. The surface antigen is the coat protein of hepatitis B virus, and it is not contagious by itself, but its appearance is often accompanied by the presence of hepatitis B virus, so its positive is a sign that it has been infected with hepatitis B virus. Normally, serum is detected in the serum 2-6 months after infection, and serum transaminase has not risen. Most patients with acute hepatitis B can turn negative in the early stage of the disease, but chronic hepatitis B patients will continue to be positive. Surface antibodies are immunological and protective antibodies against hepatitis B virus in the body, and are mostly positive during the recovery period. At the same time, the majority of those receiving hepatitis B vaccine were also positive. The e antigen is usually positive after the hepatitis B virus infection, while the surface antigen is positive, or a few days later. e antibody positive appeared several months after the antigen turned negative. The core antibody is usually detected in the serum 3-5 weeks after the appearance of the surface antigen.
