About Hepatitis B Surface Antigen Lab Test in Clovis
Hepatitis B Surface Antigen (HBsAg) is a viral protein that circulates in the bloodstream during active hepatitis B infection.
The surface antigen is the first detectable marker after exposure to the hepatitis B virus, typically appearing weeks before symptoms or liver enzyme elevations. Its persistence beyond six months distinguishes chronic infection from the acute form, which resolves spontaneously in most adults.
Laboratories use immunoassay techniques to identify HBsAg in serum or plasma. A reactive or positive result generally prompts additional testing, such as the hepatitis B surface antibody and core antibody, to clarify whether the infection is acute, chronic, or resolving.
Because the surface antigen can be present even when a person feels well, this test is used in routine screening, prenatal care, and evaluation of individuals with elevated liver enzymes or known exposure risk. A negative result usually indicates the absence of active infection, though it does not by itself confirm immunity.
