Performance of QuantiFERON TB gold test compared with the tuberculin skin test for detecting latent tuberculosis infection in lung and heart transplant candidates.

Objectives: Evaluation for latent tuberculosis infection is advised before organ transplant. The interferon-gamma release assay has been shown to be more specific than the tuberculin skin test for screening for latent tuberculosis infection. We compared the tuberculin skin test and QuantiFERON-TB Gold In-Tube test for screening for latent tuberculosis infection and agreement between the tests in heart and lung transplant recipients before transplant.
