No, it means that you are immune for HBV, HBsAb 1000 is a very good result. You've been probably vacinaded or you passed accute HBV and your body healed itself and you'll have antibodies for the rest of your life
If you have been vacinated you may check your HBsAb after a few years to make sure it still has a high level, otherwise it would be good to get vacinated again.
