About Hepatitis B Surface Antigen Lab Test in Bothell
Hepatitis B surface antigen (HBsAg) is the first viral marker to become detectable after exposure to the hepatitis B virus, often appearing before symptoms or liver enzyme changes.
The surface antigen is a protein component of the virus's outer coat. When the virus is actively replicating, this protein is shed into the bloodstream in quantities large enough to be measured by immunoassay. A reactive result therefore signals that the virus is present and the person is capable of transmitting it to others.
During acute infection, HBsAg typically becomes detectable weeks before symptoms such as fatigue, jaundice, or abdominal discomfort appear, and it usually clears within a few months as the immune system resolves the infection. If the antigen remains detectable beyond six months, the infection is classified as chronic, a state that can persist silently for decades and carries long-term risks to liver health.
Because the surface antigen can be present without obvious symptoms, testing is used both to evaluate people with concerning signs or known exposure and to screen those whose history suggests risk. Results are interpreted alongside other hepatitis B markers and liver function tests, so a single reactive or nonreactive finding is best understood in the context of the full clinical picture.
