Evaluation of the performance of two tuberculosis interferon gamma release assays (IGRA-ELISA and T-SPOT.TB) for diagnosing Mycobacterium tuberculosis infection

摘要

This data contains information from 3727 patients and shows the performance of two IGRAs tests (T-SPOT.TB and IGRA-ELISA) used in China for screening and diagnostic Mycobacterium tuberculosis infection. The positive results were divided into four groups according with the test values, and the proportions of positives in each group were compared. The positive predictive values (PPVs) at different cutoffs for diagnostic active TB and value change trend for the two IGRAs tests were analyzed.
