About Hepatitis B Surface Antigen Lab Test in Wheaton
This assay is a cornerstone of hepatitis B screening and diagnosis, used to identify people who are currently infected and capable of transmitting the virus to others.
Hepatitis B surface antigen, often abbreviated HBsAg, becomes detectable in the blood before symptoms of acute hepatitis B appear and before the body mounts an antibody response. In acute infection, the antigen typically persists for several weeks to a few months and then clears as the immune system resolves the infection.
When HBsAg remains detectable for longer than six months, the infection is classified as chronic. Chronic hepatitis B can be asymptomatic for decades while still affecting the liver, which is why antigen testing is used both in initial screening and in monitoring people with known infection.
A positive result does not, by itself, distinguish acute from chronic infection; that distinction depends on how long the antigen has been present and on additional markers such as IgM antibodies to the core antigen. A negative result generally indicates that no surface antigen is circulating, though it cannot rule out very early infection or prior resolved infection.
