In this study, we compared the predictive value of IGRAs to the TST for progression to tuberculosis disease in children, including those &amp;lt;5 years old.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS:<\/jats:title>\n                  <jats:p>Children &amp;lt;15 years old at risk for LTBI or progression to disease were tested with TST, QuantiFERON-TB Gold In-Tube test (QFT-GIT), and T-SPOT.TB test (T-SPOT) and followed actively for 2 years, then with registry matches, to identify incident disease.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>Of 3593 children enrolled September 2012 to April 2016, 92% were born outside the United States; 25% were &amp;lt;5 years old. Four children developed tuberculosis over a median 4.3 years of follow-up. Sensitivities for progression to disease for TST and IGRAs were low (50%\u201375%), with wide confidence intervals (CIs). Specificities for TST, QFT-GIT, and T-SPOT were 73.4% (95% CI: 71.9\u201374.8), 90.1% (95% CI: 89.1\u201391.1), and 92.9% (95% CI: 92.0\u201393.7), respectively. Positive and negative predictive values for TST, QFT-GIT, and T-SPOT were 0.2 (95% CI: 0.1\u20130.8), 0.9 (95% CI: 0.3\u20132.5), and 0.8 (95% CI: 0.2\u20132.9) and 99.9 (95% CI: 99.7\u2013100), 100 (95% CI: 99.8\u2013100), and 99.9 (95% CI: 99.8\u2013100), respectively. Of 533 children with TST-positive, IGRA-negative results not treated for LTBI, including 54 children &amp;lt;2 years old, none developed disease.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>Although both types of tests poorly predict disease progression, IGRAs are no less predictive than the TST and offer high specificity and negative predictive values.
