Hepatitis B is caused by HBV( Hepatitis B virus) that can affect the liver. The surface antibody (Anti-HBs) is a protective antibody your body makes after recovering from hepatitis B infection or after vaccination. The Anti-HBs test measures the level of this protective antibody in your blood. It shows whether you are immune to hepatitis B, either from past infection or from vaccination.

Before the Test

Tell your doctor about your vaccination history and any past hepatitis infection.

This test checks antibody levels post infection or vaccination, cannot be detected in active infection; other tests are used to detect current infection.

Fasting is not required.
