Quick answer
This test looks for the hepatitis B surface antigen in a blood sample. HBsAg is one of the earliest markers to appear after infection and is used to help identify acute or chronic hepatitis B. A healthcare provider interprets the result with other markers and the clinical picture.
What this test measures
The hepatitis B surface antigen is a protein on the outer coat of the virus. Its presence generally indicates that the virus is in the blood and can be an early sign of infection. If HBsAg remains detectable over time, a clinician may evaluate for chronic hepatitis B.
A routine blood draw provides the serum for analysis. The laboratory reports HBsAg, and results are often combined with anti-HBs, anti-HBc total, anti-HBc IgM, HBeAg, anti-HBe, and HBV DNA. Together, these markers describe the stage of infection and whether the immune system has responded.
Testing is commonly requested after possible exposure, during screening programs, in pregnancy care, or when liver symptoms need evaluation. The result does not stand alone; a qualified healthcare provider determines what the pattern of markers means for diagnosis and follow-up.
