About Hepatitis B Surface Antigen Lab Test in Fallbrook
Hepatitis B Surface Antigen testing provides a direct look at active viral presence rather than indirect immune response.
Hepatitis B is a DNA virus transmitted through contact with infected blood or bodily fluids. After exposure, the surface antigen typically becomes detectable before symptoms appear and before the body mounts a measurable antibody response.
In acute infection, the surface antigen usually remains detectable for several weeks to months, then clears as the immune system resolves the infection. If the antigen persists beyond six months, the infection is classified as chronic.
The test is often ordered alongside other hepatitis markers, such as core antibodies and surface antibodies, to distinguish between acute infection, chronic infection, resolved infection, and immunity from vaccination. Results should be interpreted by a qualified healthcare professional in the context of the full clinical picture.
