HBV is a contagious virus that attacks the liver and can be spread through contact with infected blood and other bodily fluids.¹ Although the HBV vaccine is widely available, many adults remain unvaccinated and therefore unprotected against HBV infection. Labcorp OnDemand’s Hepatitis B Immunity Test can determine your HBV immunity status due to either a prior resolved infection or vaccination.
Note: This test is not intended to be used to diagnose a current active Hep B infection. Those with any symptoms of Hep B infection should contact a health care provider for next steps.
Preparation: No special preparation needed.
Consider getting tested if you are unsure if you have received your hepatitis B vaccines or you want to find out if you are still immune from a previous vaccination or prior resolved infection.

If you were immunized earlier in life, your immunity to HBV may have declined over time.³
This test helps determine if you are protected, especially if you are at high risk for exposure to HBV. So, it’s important to be proactive and determine your immunity.

● Individuals needing proof of immunity status to HBV for work, travel or school
● Individuals who are unsure if they’ve ever been vaccinated against HBV (e.g., lost vaccine records)
● Individuals at increased risk for HBV that want to ensure they are as protected as possible from infection
Please note: this test measures your antibody levels in order to determine your immunity to HBV. This test does NOT screen for active infection of hepatitis B.
Per CDC guidelines², the following individuals are at greater risk of exposure to hepatitis B:
• Individuals who inject drugs or share needles, syringes and other drug equipment
• Sex partners of individuals with HBV
• Men who have sex with men
• Individuals who live with someone who has HBV
• Healthcare and public safety workers exposed to blood on the job
• Individuals on dialysis
Your test results will indicate whether or not you are immune to HBV infection.
Healthy people who received their vaccine in infancy are likely to be protected against HBV infection for 30 years or more. Because immunity declines over time, people at higher risk for exposure to HBV (healthcare workers, immunocompromised patients, people who have an intimate partner with chronic HBV infection, etc.) may desire periodic testing to ensure they continue to be protected against infection.
If your results suggest that you are not immune, you should consult with your provider to determine if HBV vaccination (or a booster for those previously vaccinated with ongoing risk for exposure) is in your best interest.
