In non endemic countries or correctly referred as low burden tuberculosis countries, screening using Mantoux/IGRA has been advised (look up CDCs guidelines, especially the one on primary care). Chest x-ray does not reveal much but occasional hilar lymphadenopathy indicative of latent tuberculosis.

 Ultimately it all boils down to whether you are going to prophylactically treat a patient detected with latent tuberculosis. This would be relevant in a non endemic country but controversial in endemic countries.

 A combination of Mantoux and IGRA has been seen as economical. You can read my papers to find sources related to this comment.

 Hope my perspective has been helpful.
