About Hepatitis B Surface Antigen Lab Test in Berkeley
This panel measures the hepatitis B surface antigen, a viral protein that appears in the blood during active infection.
Hepatitis B surface antigen, often abbreviated HBsAg, is a component of the virus's outer coat. It becomes detectable in the blood before symptoms appear and before the body mounts a measurable antibody response.
A reactive result generally means the virus is present. In acute infection, the antigen typically clears within a few months as the immune system resolves the infection. If it remains detectable beyond that window, the infection is considered chronic.
The test is used to screen for infection, to evaluate people with symptoms or abnormal liver tests, and to monitor those known to carry the virus. Results are interpreted alongside other hepatitis B markers such as antibodies and viral DNA.
