Not necessarily: Your body makes hep b surface antibody in response to the hepatitis b vaccine. It can also make it to the hepatitis b virus. If you've been vaccinated, it's more likely to be due to the first reason. If you're still concerned though, a test for hep b surface antigen and a liver function panel should clear things up. Most likely, they were checking your immunity status.

No: Need not worry. That just mean you are protected. You have the antibody against hepatitis b!

... and if there is any active circulating hepatitis B antigen, you could have ongoing hepatitis and/or the possibility of exposing others to same.

would recommend further workup, to see if there is any active circulating hepatitis B antigen. If you have not had hepatitis B vaccination -- then you, at some point, have been exposed to hepatitis B (which spreads via blood or sexual contact). It might be useful to track this backwards, potentially help and inform your previous viral "donor".
