Once a positive ppd,always a positive post treatment,it is not recommended to repeat ppd....however the newer tests for latent tuberculosis like quantiferon TB gold test would become negative after treatment.
This is my understanding,as the CDC guidelines say that once u have a positive ppd,u never repeat it.However please reconfirm it.
