About Hepatitis B Surface Antigen Lab Test in Covina
Understanding what the surface antigen reveals helps clarify why this marker is central to hepatitis B testing.
Hepatitis B surface antigen, often abbreviated HBsAg, is a protein found on the viral envelope. It becomes detectable in the blood before other markers of infection and remains present during active viral replication.
A reactive or positive result generally means the virus is present and the person can transmit it to others. A non-reactive or negative result usually indicates that the virus is not detected, though timing and other markers may be needed to interpret the full picture.
Because the surface antigen can persist for more than six months in some individuals, it serves as a key indicator of chronic hepatitis B. Additional tests, such as antibodies and viral DNA, are often used alongside it to assess infection status and liver health.
