About Hepatitis B Surface Antigen Lab Test in Calexico
Understanding what the hepatitis B surface antigen represents helps clarify why this test is a cornerstone of hepatitis B screening and monitoring.
The hepatitis B surface antigen, often abbreviated HBsAg, is a protein found on the surface of the hepatitis B virus. When the virus is present and replicating in the body, this antigen can be detected in the bloodstream. It typically appears before other markers of infection and remains detectable throughout the course of an active infection.
A reactive or positive HBsAg result generally indicates that the person is currently infected with hepatitis B and can transmit the virus to others. The test does not by itself distinguish between an acute infection, which may resolve on its own, and a chronic infection, which persists for six months or longer. Additional testing and clinical evaluation are needed to make that distinction.
A non-reactive or negative HBsAg result usually means no hepatitis B surface antigen was detected at the time of testing. However, results must be interpreted in context. A person in the early incubation period or with very low levels of the virus might test negative. Healthcare providers may order other hepatitis B tests, such as antibodies or viral DNA, to complete the picture.
