Negative Tuberculin Skin Test and Prediction of Reversion of QuantiFERON Interferon Gamma Release Assay in US Healthcare Workers INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY Thanassi, W., Noda, A., Hernandez, B., Friedman, L., Dorman, S., Yesavage, J. 2016; 37 (4): 478-482
Abstract
QuantiFERON tuberculosis tests (QFT) reverted in (612) 77% of 1,094 low-risk healthcare workers (HCW) testing less than 1.16 IU/mL. Of HCW testing greater than 1.1 IU/mL, 33 (59%) of 56 with negative tuberculin skin tests (TST) reverted vs 8 (6%) of 125 with positive TSTs. Retesting low-risk QFT-positive and TST-negative HCW is prudent.
