Accuracy of VIDASⓇ TB-IGRA in TB patients and individuals with different thresholds of exposure

OBJECTIVES: TB-IGRA (bioMérieux) is a fully automated assay recently developed. We report here the results of a global, multicenter, cross-sectional, prospective study to evaluate the diagnostic accuracy of the assay. METHODS: -Plus, QIAGEN). RESULTS: ‑Plus. CONCLUSIONS: TB-IGRA was significantly more sensitive without a reduction in specificity, and it correlated better with an exposure gradient, suggesting that it is a valuable tool for TBI diagnosis.
