1 (hbsag-hepatitis b virus surface antigen) is a sign of being infected with the virus and does not reflect whether the virus has replicated, the degree of replication, or the infectivity

2 (hbsab-hepatitis b virus surface antibody) is a neutralizing antibody marker and is the main marker 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 rely on their own immunity to clear the hepatitis b virus after being infected with the hepatitis b virus will also produce hepatitis b surface antibodies, which is a good phenomenon.

3 (hbeag-hepatitis b virus e antigen) is a viral replication marker. if it remains positive for more than 3 months, it will tend to become chronic.

4 (hbeab-hepatitis b virus e antibody) is the stop sign of virus replication. virus replication is reduced, and the infectivity is weaker than that of hbv virus model (2 pictures), but it is not completely non-infectious.

5 (hbcab-hepatitis b virus core antibody) is a sign that appears in people who have been infected or are currently infected. core antibody igm is a sign of recent infection or virus replication, and core antibody igg is produced after infection, which is of certain significance for assisting two-and-a-half examinations.
