About Hepatitis B Surface Antigen Lab Test in Pasadena
Hepatitis B Surface Antigen (HBsAg) is the earliest serological marker of hepatitis B virus infection, appearing before symptoms or liver enzyme elevations in many cases.
The test works by using antibodies that bind specifically to HBsAg in a blood sample. A reactive result indicates that the virus is present and the person can transmit it to others.
During acute infection, HBsAg typically becomes detectable weeks before symptoms and remains positive for several weeks to months. If it persists beyond six months, the infection is classified as chronic.
HBsAg testing is used for screening, diagnosis, and monitoring. It is often paired with other hepatitis B markers to clarify the stage of infection and guide clinical decisions.
