About Hepatitis B Surface Antigen Lab Test in Berkeley
Hepatitis B Surface Antigen (HBsAg) is the first viral marker to appear after exposure to the hepatitis B virus, making it a primary tool for identifying acute infection.
The surface antigen is a component of the virus's outer coat. When the virus is present and replicating, this antigen can be detected in the bloodstream, often before symptoms arise or liver enzymes become abnormal.
In acute infection, HBsAg typically becomes detectable within weeks of exposure and remains positive during the active phase. Its continued presence beyond six months generally indicates chronic hepatitis B, a condition that can lead to long-term liver complications.
This test is often used alongside other hepatitis B markers, such as antibodies and viral DNA, to clarify the stage of infection, distinguish acute from chronic disease, and guide clinical monitoring. Results should be interpreted by a qualified healthcare professional in the context of the full clinical picture.
