Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test is a blood test used to detect a specific protein that appears on the outer shell of the hepatitis B virus.

About Hepatitis B Surface Antigen Lab Test in Ontario
Hepatitis B Surface Antigen is a protein found on the surface of the virus, and its detection is central to identifying an active infection.
The hepatitis B virus is a DNA virus that infects the liver. The surface antigen, often abbreviated HBsAg, is a component of the viral envelope. When the virus is replicating in the body, this antigen can be detected in the bloodstream, typically within a few weeks after exposure and before symptoms appear.
Testing for the surface antigen helps distinguish an active infection from prior exposure or vaccination. A positive result generally means the person is currently infected and can transmit the virus to others. A negative result usually indicates no active infection, though it does not by itself confirm immunity.
Follow-up testing may include other hepatitis B markers, such as antibodies or viral DNA, to clarify whether the infection is acute or chronic. Chronic infection is defined by the persistence of the surface antigen for six months or longer.
