Casas S et al. – QuantiFERON–TB Gold in–Tube (QFT–GIT) is useful for identifying immune–mediated inflammatory diseases patients requiring treatment of latent tuberculosis before anti–tumor necrosis factor therapy. However, given the poor agreement between tuberculin skin test and QFT–GIT, authors advocate a strategy of simultaneous testing to optimize diagnostic sensitivity.
