About Hepatitis B Surface Antigen Lab Test in Oxnard
This assay identifies the surface antigen (HBsAg), a key component of the hepatitis B virus envelope that the immune system recognizes during infection.
Hepatitis B surface antigen is a protein embedded in the viral envelope. It is the first detectable marker after exposure to the virus, often appearing before symptoms or liver enzyme elevations.
A positive result generally means the virus is present and the person can transmit it to others. In acute infection, the antigen typically clears within a few months as the immune response resolves the virus. If it remains detectable beyond six months, the infection is classified as chronic.
Clinicians use this test to screen for infection, evaluate acute hepatitis, monitor chronic hepatitis B, and assess whether a person is infectious. It is often ordered alongside other hepatitis B markers, such as surface antibody and core antibody, to clarify the stage of infection or immunity.
