A member asked:
My hep b surface antibody came back reactive, what does this mean?
A doctor has provided 1 answer
If that's the only positive result, i.e. negative tests for surface antigen (HBsAg) and hep B core antibody (HBcAb), it means you were vaccinated in the past and are immune to the virus.
