I tested pos. to hep b surface antibody and i was reactive to hep. b core antibody?

i really need help on this one, i just had blood work done, and the nurse calls me and tells me that ive tested positive to the hepatitis b surface antibody and reacted to the hepatitis b core antibody, she sent me my labs, on the surface antibody it has a # greater than 2000 next to it, i have never been a drug user, etc, i am a retired correctional officer, can someone please explain in detail what this test means to me, i am seeing the dr. in 3 weeks and they are going to retest my blood again i know that the normal range for the surface antibody is less than 0.85 and im showing greater than 2000, the anxiety is killing me!!!!
