Hepatitis B surface antigen (HBsAG) Detects protein that is present on the surface of the virus.  It is used to screen for, detect, and help diagnose acute and chronic hepatitis B virus (HBV) infections; earliest routine indicator of acute hepatitis B and frequently identifies infected people before symptoms appear; undetectable in the blood during the recovery period; it is the primary way of identifying those with chronic infections, including "hepatitis B virus (HBV) carrier" state.

Clinical Significance

Surface antigen usually appears in the serum after an incubation period of 1 to 6 months following exposure to Hepatitis B virus and peaks shortly after onset of symptoms. It typically disappears within 1 to 3 months. Persistence of Hepatitis B surface antigen for greater than 6 months is a prognostic indicator of chronic Hepatitis B infection.
