Hepatitis B antibodies, including hepatitis B surface antibody, hepatitis B e antibody and hepatitis B core antibody. Hepatitis B surface antibody is a protective antibody. When the hepatitis B surface antibody is positive, it means that it has a protective effect on the body and can prevent infection with the hepatitis B virus. If the hepatitis B surface antibody is negative, the hepatitis B vaccine can be administered to produce a positive hepatitis B surface antibody, which provides protection to the body. Hepatitis B core antibody is an indicator of previous infection. If you have been infected with the hepatitis B virus, you will have a positive hepatitis B core antibody. When the hepatitis B e antibody is positive, it means that the person is in a small triple-positive state, and usually the hepatitis B virus replication is relatively low or in a quiescent stage in this case.
