Its presence is the earliest serological marker of acute hepatitis B infection and can also signal chronic infection.
About Hepatitis B Surface Antigen Lab Test in Prosper
This test identifies the hepatitis B surface antigen (HBsAg), a key marker in the body's immune response to the virus.
Hepatitis B surface antigen appears in the blood before other detectable markers of infection, making it useful for early identification of acute cases. In individuals who do not clear the virus, HBsAg can persist beyond six months, indicating a chronic infection.
The test is performed on a blood sample and requires no special preparation beyond following the laboratory's standard instructions. Results are typically available within one to three business days.
Because HBsAg can be detected even when symptoms are absent, it serves as a reliable screening tool for hepatitis B. A positive result does not by itself distinguish between acute and chronic infection; that determination depends on repeat testing over time and additional markers.
