The basic blood test for hepatitis B screening consists of three screening tests: a hepatitis B surface antigen test, which determines whether a person currently has the infection; a hepatitis B core antibody test, which determines whether a person has ever been infected; and a hepatitis B surface antibody test, which determines whether a person has cleared the virus after infection, or has been vaccinated and is now immune to future infections.

Presence of antibodies to the HBsAg Antigen , that is the HBs-Antibody is indicative of acquired immunity to the infection. This is a good thing, and nothing to be worried about.
