Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen Lab Test is a blood test designed to detect a specific protein that appears on the outer shell of the hepatitis B virus. Its presence in the bloodstream is a direct signal that the virus itself is present, making this test a foundational tool in identifying an active hepatitis B infection.
About Hepatitis B Surface Antigen Lab Test in Rosemead
Understanding what the surface antigen reveals helps clarify why this test is often the first step in evaluating hepatitis B status.
The hepatitis B surface antigen, commonly abbreviated as HBsAg, is a protein found on the virus's outer envelope. When the virus is actively replicating in the body, this antigen is released into the blood, where it can be detected by a laboratory assay. Its appearance typically precedes the development of antibodies and can be identified before symptoms arise, which is why it is considered an early marker of infection.
A positive result generally indicates that the person is currently infected with hepatitis B and can transmit the virus to others. The infection may be acute, meaning it is recent and may resolve on its own, or chronic, meaning it persists for longer than six months. Distinguishing between these states usually requires additional testing and monitoring over time, as the surface antigen alone does not reveal the full clinical picture.
This test is frequently used in several contexts: screening individuals who may have been exposed, evaluating people with abnormal liver function, and monitoring those known to have chronic hepatitis B. Because the surface antigen can appear early and remain detectable in chronic cases, it serves as a reliable indicator of active viral presence rather than a marker of past, resolved infection or immunity from vaccination.
