About Hepatitis B Surface Antigen Lab Test in Decatur
This test measures the hepatitis B surface antigen (HBsAg), a viral protein that signals active infection.
Hepatitis B surface antigen is a protein found on the outer coat of the hepatitis B virus. When the virus is present and replicating, this antigen can be detected in the bloodstream, often before symptoms appear and before other markers become positive.
A positive result generally indicates that the virus is present and the person can transmit it to others. In acute infection, the antigen typically appears early and may clear as the immune system resolves the infection. If it remains detectable for an extended period, it suggests chronic hepatitis B infection.
The test is commonly used to screen for hepatitis B, to evaluate people with symptoms or abnormal liver tests, and to monitor those known to carry the virus. Results are interpreted alongside other hepatitis B markers and clinical information, since the antigen alone does not show whether the infection is acute or chronic or how infectious a person may be.
