[Correspondence] Incidence of active tuberculosis in rural China

Lei Gao and colleagues1 report that high-risk populations in communities in rural China should be targeted for latent infection screening and treatment with an interferon- γ releasing assay through use of QuantiFERON-TB Gold In-Tube (QFT) instead of a tuberculin skin test. In their population-based cohort study,1 the values of QFT results were dichotomised into QFT-positive or QFT-negative as recommended by the manufacturer through use of a traditionally used cutoff value of 0·35 IU/mL or higher for QFT-positive.
