About Hepatitis B Surface Antigen Lab Test in Riverside
This assay identifies the surface antigen (HBsAg), a component of the viral envelope that circulates in the bloodstream during active infection.
Hepatitis B surface antigen is the first detectable viral marker after exposure, typically appearing weeks before symptoms or liver enzyme elevations. Its persistence beyond six months distinguishes chronic infection from an acute, resolving one.
The test is used to screen for active infection, evaluate donor blood, and monitor people at risk of liver inflammation. A reactive result does not by itself indicate severity or liver damage; it confirms that the virus is present and potentially transmissible.
Because the surface antigen can be detected before antibodies form, it serves as a primary screening tool. Follow-up testing, including antibody and nucleic acid assays, helps clarify the stage of infection and guide clinical interpretation.
