Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test detects a protein that appears on the outer shell of the hepatitis B virus. Its presence in the blood is the earliest serological signal of an active hepatitis B infection, whether acute or chronic, and it is therefore a cornerstone of viral hepatitis screening and monitoring.
About Hepatitis B Surface Antigen Lab Test in Leawood
Hepatitis B surface antigen testing answers a specific question: is the virus currently present in the body?
The surface antigen, often abbreviated HBsAg, is produced by the virus and circulates in the bloodstream during active infection. It can be detected before symptoms appear and before the immune system mounts a measurable antibody response, which is why it is used as an early marker of acute hepatitis B.
When HBsAg remains detectable for longer than six months, the infection is classified as chronic. Chronic hepatitis B can persist silently for years, so the test is also used to monitor people with known exposure or ongoing risk and to confirm whether the virus has cleared.
A negative result generally indicates that the virus is not currently detectable, though it does not by itself prove immunity. A positive result is typically followed by additional tests, such as antibody panels and viral load measurements, to clarify the stage of infection and guide clinical decisions.
