About Hepatitis B Surface Antigen Lab Test in Simi Valley
This profile measures hepatitis B surface antigen (HBsAg), a marker used to identify current infection with the hepatitis B virus.
HBsAg is the first detectable viral marker after exposure to hepatitis B, typically appearing before symptoms or liver enzyme changes. Its detection indicates that the virus is present and the person can transmit it to others.
The test distinguishes active infection from resolved or vaccinated status. A positive result may reflect acute infection or chronic carriage, while a negative result generally means the virus is not currently detectable, though window periods and rare variants exist.
Clinicians use this profile alongside other hepatitis B markers and liver function tests to stage infection, guide monitoring, and inform decisions about care and prevention.
