About Hepatitis B Surface Antigen Lab Test in Normal
This test is used to identify current hepatitis B infection, whether acute or chronic.
Hepatitis B surface antigen, often abbreviated HBsAg, is a component of the virus's outer coat. When the antigen is found in a blood sample, it indicates that the hepatitis B virus is present and that the person can transmit the infection to others.
The surface antigen is typically the first detectable marker after exposure to the virus. In acute infection, it becomes positive before symptoms appear or liver enzyme elevations are noted. If the antigen remains detectable for longer than six months, the infection is classified as chronic.
Results are interpreted alongside other hepatitis B markers and liver function tests. A positive result generally calls for follow-up testing to clarify the stage of infection and to guide appropriate medical evaluation. A negative result usually means no current infection, though it does not by itself confirm immunity from vaccination or past infection.
