Anti-HBs measures antibody against hepatitis B surface antigen. A positive result commonly reflects immunity, but additional markers distinguish vaccine-related immunity from past infection.
What should you know?
HBsAg and total anti-HBc are important. In certain groups, anti-HBs of at least 10 mIU/mL measured one to two months after completing vaccination indicates a protective response; routine repeat tests are not needed for everyone.
Practical steps
- Prepare your vaccination record and test dates.
- Review HBsAg and anti-HBc alongside the result.
- Ask about individualized monitoring if you work in health care or are immunocompromised.
When to seek professional assessment
Positive HBsAg, jaundice or abnormal liver tests require medical evaluation rather than interpretation of anti-HBs alone.
Frequently asked question
Does positive anti-HBs mean I have hepatitis B?
Usually not. It often shows immunity; other markers clarify the situation.
