Tuberculosis: Your treatment with inh is unlikely to have eliminated all of these organisms. It is meant to reduce the risk of recrudescent infection after having had primary exposure. Mycobacterium tuberculosis will live in your body for lifetime without symptoms if you are fortunate, and the positive quantiferon is evidence of its presence. You should be fine, but tell any doctors you see that you're positive.

If you are having fever, cough, weight loss, or anything similar persistently would suggest that you go and see a doctor and be evaluated. No way in which to assess this over the internet.

Re-exposure.: This likely means you have been re exposed to tb. Administration of the test implies that you should be treated although this may not be the case. You should check with your doctor. There is an on-line tool that may help you understand the results. www.tstin3d.com.
