A member asked:

How long is a chest x-ray for a positive ppd good for?

A doctor has provided 1 answer

As long as you like: The procedure of yearly cxrs in PPD positive workers is archaic since if reactivation occurs, so will symptoms. It is a needless risk of radiation. Although if never done, a base line cxrs is reasonable.
