Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test is a blood-based assay that detects a protein found on the outer envelope of the hepatitis B virus. Its presence is a direct marker of viral infection, and it holds a specific place in the timeline of hepatitis B testing: it is often the first serological signal to appear after exposure.
About Hepatitis B Surface Antigen Lab Test in Hammond
Hepatitis B Surface Antigen (HBsAg) is the earliest detectable serological marker of hepatitis B virus infection.
When the virus enters the bloodstream, the surface antigen can be identified before the body mounts a measurable antibody response. This early window makes HBsAg a primary screening tool for acute infection.
The antigen persists in chronic hepatitis B, where the immune system fails to clear the virus. A positive result that remains detectable beyond six months generally distinguishes chronic infection from an acute, resolving case.
Because the surface antigen is distinct from surface antibodies, the two markers tell different stories: antigen presence points to current infection, while antibody presence typically signals immunity or recovery. Clinicians use this distinction to interpret the full hepatitis B panel.
