Hepatitis B two-pair half self-test

1 (HBsAg-Hepatitis B virus surface antigen) is a sign of virus infection, and does not reflect whether the virus replicates, the degree of replication, or the strength of its infectiousness

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

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

4 (HBeAb-Hepatitis B virus e antibody) is a sign of stopped virus replication. The virus replication is reduced, and the infectiousness is weaker than 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.
