About Hepatitis B Surface Antigen Lab Test in St. Augustine
Hepatitis B surface antigen (HBsAg) is a protein on the viral envelope that the immune system recognizes as foreign.
When the virus enters the bloodstream, HBsAg typically appears before other markers such as antibodies, making it useful for early detection of infection.
A positive result generally means the person is infected and can transmit the virus to others. Additional testing, including antibody and viral load assays, helps distinguish acute from chronic infection.
A negative result usually indicates no current infection, though it may also reflect a window period before the antigen becomes detectable or after it has cleared. Interpretation should always be made by a qualified healthcare professional in the context of the full clinical picture.
