About Hepatitis B Surface Antigen Lab Test in Manhattan Beach
Hepatitis B Surface Antigen (HBsAg) is a protein found on the outer envelope of the hepatitis B virus. When the virus is present in the bloodstream, this antigen becomes detectable, often before symptoms appear or liver enzyme levels rise.
The test works by using antibodies that bind specifically to HBsAg in a blood sample. If the antigen is present, the reaction produces a measurable signal, confirming active infection. Because HBsAg appears early and remains detectable during both acute and chronic phases, it serves as a primary screening marker for hepatitis B.
A positive HBsAg result generally means the person is infected with hepatitis B and can transmit the virus to others. In acute infection, the antigen typically disappears as the immune system clears the virus, often followed by the appearance of antibodies. If HBsAg persists for six months or longer, the infection is classified as chronic.
Additional tests, such as hepatitis B surface antibody and core antibody, help distinguish between acute infection, chronic infection, past resolved infection, and vaccination status. Healthcare providers interpret HBsAg results alongside these markers and the person's clinical history to determine the appropriate next steps.
