Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen Lab Panel is a blood test designed to detect the presence of the hepatitis B surface antigen, a protein that appears on the outer surface of the virus. Its presence is the earliest serological marker of acute hepatitis B infection and can also indicate chronic infection when it persists over time.
About Hepatitis B Surface Antigen Lab Test in Norwalk
Understanding what the hepatitis B surface antigen reveals 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 viral envelope. When the virus is actively replicating, this antigen becomes detectable in the bloodstream, typically appearing before symptoms or liver enzyme elevations in acute infection.
In acute hepatitis B, HBsAg is usually the first marker to appear, rising within weeks of exposure and declining as the immune system clears the virus. If HBsAg remains detectable for longer than six months, the infection is classified as chronic, which carries different long-term health implications.
Clinicians use this test alongside other hepatitis B markers, such as antibodies and viral DNA, to distinguish between acute infection, chronic infection, resolved infection, and immunity from vaccination. Because the surface antigen is specific to the virus, its detection provides direct evidence of current infection rather than past exposure or vaccine-induced immunity.
