Why This Biomarker Matters

HBsAb confirms immunity to hepatitis B through vaccination or prior infection. Absence suggests need for vaccination to prevent a serious liver disease.

Overview

Hepatitis B surface antibody (HBsAb) appears after successful vaccination or recovery from hepatitis B infection. A positive HBsAb indicates immunity to hepatitis B virus. This test is used to confirm immune response after vaccination and to assess protection status. Healthcare workers, blood donors, and others at risk are routinely tested. The presence of this antibody means you are protected against hepatitis B infection.
