About Hepatitis B Surface Antigen Lab Test in Bothell
Hepatitis B Surface Antigen is the earliest detectable sign of hepatitis B infection in the blood.
The hepatitis B virus is a small DNA virus that infects liver cells. During active infection, the virus produces large quantities of surface antigen, a protein embedded in its outer envelope. Laboratory testing uses an immunoassay to capture and detect this antigen in a blood sample.
Because the surface antigen appears before the body mounts a full immune response, it can be found early in acute infection. In some people, the antigen remains detectable for longer than six months, which defines chronic hepatitis B infection. The test does not distinguish between acute and chronic infection on its own; the duration of antigen positivity provides that context.
Results are reported as reactive or nonreactive, sometimes with a confirmatory neutralization step. A nonreactive result generally means the antigen was not detected. A reactive result indicates that hepatitis B surface antigen is present and warrants follow-up testing to clarify the stage of infection and guide clinical decisions.
