About Hepatitis B Surface Antigen Lab Test in Hazelwood
Hepatitis B surface antigen testing sits at the center of hepatitis B screening and monitoring.
The surface antigen, often abbreviated HBsAg, appears in the blood before other markers of hepatitis B infection and remains detectable while the virus is actively replicating. A reactive result generally means the person is infected and can transmit the virus to others.
Clinicians use this test to distinguish an active infection from prior exposure or vaccination. Someone who has recovered from hepatitis B typically clears the surface antigen and develops antibodies against it, while a vaccinated person never carries the antigen at all.
When the antigen persists beyond six months, the infection is classified as chronic. That distinction matters because chronic hepatitis B can quietly damage the liver over time, so periodic monitoring with this and related tests helps guide follow-up care.
