i am assuming you had the vacciene?
you need to have a booster for Hepatits B, followed by a recheck of your titer in about 2-3 months. If you still test non-responder you are most likely immune. Some people do not respond by making titerable levels of antibodies for Hep B, but the CDC has tracked several of these non-responders who have had needle sticks and other bbf exposures and they do not develop Hepatits B. If you still do not respond after a booster, you will be considered a non-responder. Many hospitals (where you work) will insist on giving more boosters, they won't hurt you, but they won't turn you into a responder either.
