I was vacinated for hepatitis b 17 years ago when I was 10. Do I need to test. If so will my vacination cause a false positive?

Hepatitis B. Hepatitis B- if you received three Hepatitis B vaccines you are protected against Hepatitis B. No need to test. Blood testing would show you are hepatitis B immune not that you have active infection- no false positive.
It can be rechecked . This is something that your physician may decide wants to be checked to see if your immunization took affect.
