1 (HBsAg-Hepatitis B virus surface antigen) is a sign of viral infection and does not reflect whether the virus has replicated, the degree of replication, or the degree of infectiousness.

2 (HBsAb-Hepatitis B virus surface antibody) is a neutralizing antibody marker, which is the main indicator of recovery or resistance. For hepatitis B vaccine recipients, if only this item is positive, it should be regarded as a normal phenomenon after hepatitis B vaccination; people who are infected with hepatitis B virus and rely on their own immunity to eliminate hepatitis B virus will also produce hepatitis B surface antibodies, which is a good phenomenon.

3 (HBeAg-Hepatitis B virus e antigen) is a marker of viral replication. If it remains positive for more than 3 months, it tends to become chronic.

4 (HBeAb-Hepatitis B virus e antibody) is a sign of viral replication cessation. Virus replication is reduced, and the infectiousness is weaker than that of HBV virus pattern diagram (2 pictures), but it is not completely non-infectious.

5 (HBcAb-Hepatitis B virus core antibody) is a sign that will appear in people who have been infected or are currently infected. Core antibody IGM is a sign of recent infection or viral replication, and core antibody IgG is produced after infection, which is of certain significance in assisting the two-pair half test.
