Anyway, what's the best diagnostic exam to confirm reactivation of TB? Chest xrays are always not that reliable, think so. And so are sputum cultures if sputum collection was incorrect.

As long as the TB as been treated, then it is not considered active. There are thousands of health care workers that test positive for TB with the Mantoux Skin Test............
US Government requires the CXR for all that wish to come to the US........it is up to your employer if they wish to require the PPD once you get here, and then where you will be working in the US and with what type of population also is taken into consideration. There are some facilities that have quite a bit of TB, and if so, the infectious disease doctors there will require that you have treatment if you test positive, even if you had BCG as a child. Their opinion is that after 15 years or so, you would only be positive if you were in contact with people in the past that were positive and developed an antibody to it, but were unaware of it. Examples of this are VA hospitals, as well as many county facilities.............but they usually do not do any petitioning for nurses from out of the country.
