About Hepatitis B Surface Antigen Lab Test in Belleville
Hepatitis B Surface Antigen (HBsAg) is a viral protein that circulates in the blood during active hepatitis B infection.
The surface antigen is the first detectable marker after exposure to hepatitis B virus, typically appearing before symptoms or liver enzyme elevations. Its presence confirms that the virus is actively replicating and that the person can transmit the infection to others.
In acute infection, HBsAg usually becomes undetectable within a few months as the immune system clears the virus. If the antigen remains detectable beyond six months, the infection is classified as chronic, a state that can lead to long-term liver complications.
Testing for HBsAg is used to screen for infection, evaluate unexplained liver inflammation, and monitor people at risk of exposure. Results are interpreted alongside other hepatitis B markers such as surface antibody and core antibody to distinguish current infection from past exposure or vaccination.
