i've had a hep b test done and my hep b surface ab results was reactive. what does that mean?

If that was the only positive test, then you received the HBV vaccine and are immune. If the anti-HBcore is also positive, then you had a natural infection but developed immunity. In both these situations, the HBs antigen is negative.
