Quick Answer

A Hepatitis B titer is a blood test that measures the level of antibodies against the hepatitis B virus in your blood. It is used to check if you are immune to hepatitis B, either from vaccination or past infection. A positive result means you have protective immunity.

  • A hepatitis B titer specifically tests for hepatitis B, not hepatitis A or C.
  • The test measures antibodies called anti-HBs to confirm immunity.
  • A positive titer (≥10 mIU/mL) indicates protection against hepatitis B.
  • Hepatitis C antibodies can stay positive after treatment, but this does not mean active infection.
  • Hepatitis C can be cured with antiviral treatment, but reinfection is possible.
  • Testing is done at clinics, labs, or with at-home test kits.

The Short Version, Structured

A hepatitis B titer is a blood test that checks your immune status against the hepatitis B virus. Unlike hepatitis A (spread through contaminated food or water) or hepatitis C (spread through blood), hepatitis B is transmitted through blood, semen, or other body fluids. The titer measures specific antibodies your body produces after vaccination or infection. Knowing your titer helps determine if you need a booster vaccine or if you are protected from future infection. This test is common for healthcare workers, travelers, or anyone exposed to the virus.
