摘　　要：Background:Quick diagnosis of smear-negative pulmonary tuberculosis(TB)and extra-pulmonary TB are urgently needed in clinical diagnosis.Our research aims to investigate the usefulness of the interferon-γrelease assay(IGRA)for the diagnosis of smear-negative pulmonary and extra-pulmonary TB.Methods:We performed TB antibody and TB-IGRA tests on 389 pulmonary TB patients(including 120 smear-positive pulmonary TB patients and 269 smear-negative pulmonary TB patients),113 extra-pulmonary TB patients,81 patients with other pulmonary diseases and 100 healthy controls.Blood samples for the TB-Ab test and the TB-IGRA were collected,processed,and interpreted according to the manufacturer’s protocol.Results:The detection ratio of smear-positive pulmonary TB patients and smear-negative pulmonary TB patients were 90.8%(109 of 120)and 89.6%(241 of 269),respectively.There was no statistically significant difference of its performance between these two sample sets(P>0.05).The detection ratio of positive TB patients and extra-pulmonary TB patients were 90.0%(350 of 389)and 87.6%(99 of 113),respectively,which was not significantly different(P>0.05).Conclusions:In this work,the total detection ratio using TB-IGRA was 89.4%,therefore TB-IGRA has diagnostic values in smear-negative pulmonary TB and extra-pulmonary TB diagnosis.
