It’s important to follow your healthcare provider’s instructions and to discuss any concerns you may have about the test or its results. If you test negative for Anti-HBs, your healthcare provider may recommend re-vaccination or additional testing to determine if you have developed immunity to HBV. It’s also important to take steps to prevent the spread of HBV to others, such as practicing safe sex, avoiding sharing personal items, and getting vaccinated against HBV if you are not already immune.
