A member asked:

My ct scan reports states "calcified granulomas & fibrotic nodules. no active lesions" but i never had tb how to prove it is not tb.

A doctor has provided 1 answer

Quantiferon TB test: A normal, healthy person in such a situation can do a Quantiferon TB blood test. If the result is negative, then it is very unlikely that one had TB in the past. If both a PPD test and a Quantiferon TB test are negative, in an otherwise healthy person, that would be good evidence of not having had a TB infection.
