About Hepatitis B Surface Antigen Lab Test in Kennewick
This test looks for the hepatitis B surface antigen (HBsAg) in a blood sample. HBsAg is the earliest detectable viral protein after exposure and remains the primary screening marker for hepatitis B infection.
Hepatitis B is a viral infection that targets the liver. The surface antigen appears in the blood before other markers and can be detected even when symptoms are absent. Its presence indicates that the virus is actively replicating and that the person can transmit the infection to others.
The test is used in several contexts: screening blood donations, evaluating people with abnormal liver function, investigating possible exposure, and monitoring known cases. A positive result does not distinguish between acute and chronic infection on its own; additional tests such as antibody profiles and viral load measurements help clarify the stage and course of infection.
Results are typically reported as positive or negative. A positive HBsAg result means the virus is present and further medical evaluation is needed. A negative result generally means no current infection, though it does not confirm immunity or rule out very recent exposure before the antigen becomes detectable.
