ppd vs chest x-ray

Question

Can a current chest x-ray, which showed no evidence of disease, be used in place of a ppd for work? I am an rn. Thank you. sm

Answer

A tuberculin skin test (aka PPD) is one way to test for latent tuberculosis infection. A chest xray is not used to diagnose latent tuberculosis infection. For this reason, a current chest xray which shows no evidence of disease cannot be used "in place of a ppd for work."
