A member asked:
I had tb last 2015 but treated for 9mos. and my xray is cleared. if i will hav a pdd skin test again, will it be positive?

Positive for life: Your PPD will remain positive for as long as you live. It is not a sign of active TB. But there is no reason again have a PPD, and it could be harmful, with an aggressive reaction with an open wound and delayed healing. If a PPD is ever offered, tell them you've been treated for tuberculosis and probably they will agree it should not be done.
