Dalsor, having a positive test can be nerve racking! Talk with your PCP first. If the quantiferon gold was positive from a possible exposure at work, your employee health should be handling everything for you, it's their responsibility. Please know that you have legal rights and cannot lose your job due to a positive test. Also whIle INH is a scary idea, there are MANY drugs out there with potentials for liver issues. Again, talk honestly with your doc and make the choice that's best for you, not your employer. Take care and I wish you the best!
