The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are standard immunologic tools for LTBI detection. The aim of this study was to compare the TST results and T-SPOT(®).TB test (a type of IGRAs) in kidney transplant candidates for the screening of LTBI and follow the ...

BACKGROUND Interferon-gamma (IFN-gamma) Release Assays (IGRA) are more specific than the tuberculosis skin test (TST) in the diagnosis of latent tuberculosis (TB) infection (LTBI). We present the performance of the QuantiFERON-TB Gold In-tube (QFT-TB) assay as diagnostic test and during follow-up of preventive TB therapy in outpatients from a TB low-endemic country. METHODS 481 persons with s...

The sensitivities and specificities of the four kits were as follows: (1) Rapid test A 71.8% and 91.4% (85.5% for non-TB diseases an...
