About this test

The anti-HBs test measures antibodies against hepatitis B surface antigen, which indicate protection (immunity) against hepatitis B.

An anti-HBs level of 10 mIU/mL or higher is considered protective. Levels below 10 mIU/mL suggest no adequate immunity, and vaccination or a booster may be needed.

Immunity may come from vaccination or recovery from past infection. Interpreted with anti-HBc: anti-HBs positive with anti-HBc negative indicates vaccine immunity, while both positive indicates recovered infection.

It is important for healthcare workers, dialysis patients, and babies of infected mothers.

Questions about this test

When should I get the Anti Hbs test?

You should get an anti-HBs test 1–2 months after completing hepatitis B vaccination if you are a healthcare worker, dialysis patient, immunocompromised, or a baby born to an HBsAg-positive mother. It is also recommended after a needle-stick injury, before vaccination to check existing immunity, and to confirm recovery from hepatitis B infection.

How should I prepare for the Anti Hbs test?

No special preparation or fasting is required for an anti-HBs test. Bring your hepatitis B vaccination record with dates, as timing affects interpretation. Inform your doctor about any recent hepatitis B immunoglobulin (HBIG), blood transfusion, or IVIG, as these can give temporary antibody levels, and mention any immunosuppressive treatment.

Do I require fasting for the Anti Hbs test?

No, fasting is not required for an anti-HBs test. You can eat and drink normally before giving your sample, and the test can be done at any time of day. Bring your hepatitis B vaccination record, and inform your doctor about any recent immunoglobulin or blood transfusion.
