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 Northampton
This test looks for the hepatitis B surface antigen, a protein that appears on the virus's outer coat.
The hepatitis B surface antigen, often abbreviated HBsAg, is a protein found on the surface of the hepatitis B virus. When the virus is present in the bloodstream, this antigen can be detected by laboratory methods. It is typically the first marker to appear after exposure and remains detectable during both acute and chronic phases of infection.
Because HBsAg appears early and stays present while the virus is active, its detection helps distinguish current infection from past exposure or vaccination. A positive result generally indicates that the virus is present and the person may be able to transmit it to others. A negative result usually means no surface antigen was found at the time of testing.
Results are interpreted alongside other hepatitis B markers and clinical information. A single test cannot show the full picture of an infection, so healthcare providers may order additional tests to clarify whether an infection is acute, chronic, or resolved.
