A member asked:
If a person had tb as child and underwent treatment for it, could he have a false positive tb skin test as an adult?

Yes: Once you had a positive PPD test, it will stay positive whole your life. Chest x-ray, what you need to do every few years.

Not false +: Usually the TB skin test remains positive for a lifetime but does not reflect active infection necessarily at all.
