The outer shell of hepatitis B virus contains the surface antigen, namely HBsAg (term: hepatitis B surface antigen), and the core part contains the core antigen, namely HBcAg, The e antigen is HBEAg (medical term: hepatitis B E antigen), and the deoxyribonucleic acid of hepatitis B virus is HBV-DNA, and the deoxyribonucleic acid polymerase is DNA-P. After people are infected with hepatitis B virus, a large number of surface antigens often remain in the blood, forming surface antigenemia. The surface antigen itself is not a complete hepatitis B virus, but the shell of hepatitis B virus. It is not infectious but has antigenicity. It is just one of the signs of hepatitis B virus infection. It can indicate that you have been infected with hepatitis B virus in the past, or you are being infected with hepatitis B virus.
