The Hepatitis B Immunity Status Test is a blood test that checks whether you have protective antibodies against the hepatitis B virus. It is often ordered to confirm immunity after vaccination or to see if you have been exposed to the virus in the past.

What it measures

  • Hepatitis B surface antibody (anti-HBs) — Shows if you are immune, usually from a vaccine.
  • Hepatitis B surface antigen (HBsAg) — If positive, indicates a current infection.
  • Hepatitis B core antibody (anti-HBc) — Can show a past or ongoing infection.

Who it is for

This test is commonly ordered by primary care providers, infectious disease specialists, or sexual health clinics for people at risk of hepatitis B or those who need proof of immunity for work, school, or travel.
