PPD skin test ?
I had BCG vaccination as a child in my country, so each time I have a ppd test done it's always positive and chest Xray is required. How often do I need to have chect xray done?

This is a big problem with the USA system. Instead of giving BCG to PREVENT TB, they keep making one pay for PPD tests and X-Rays.
Provided you have a decent sized BCG scar to prove that you've been vaccinated you shouldn't have to keep having the PPD tests.

once a year is a must.
