ABSTRACT
Objective To evaluate the performance of GenoType®MTBDRplus VER2.0 kit for detecting Mycobacterium tuberculosis complex (MTBC) in sputum. Methods Sputum samples from 177 patients with suspected tuberculosis were collected, and tested by smear, MGIT liquid culture and GenoType® MTBDRplus VER2.0. When the liquid culture was positive, identification of strains was carried out. The results were statistically analyzed using SPSS 22.0, and the consistency of the count data was compared using the Kappa test. Good consistency was defined as K≥0.75. The sensitivity and specificity were applied to evaluate the performance of GenoType® MTBDRplus VER2.0 kit for detecting MTBC in sputum. Results Based on the MGIT liquid culture results,,the sensitivity, specificity, positive predictive value, negative predictive value and total coincidence rate of the GenoType® MTBDRplus VER2.0 kit was 91.67%, 95.58%, 91.67%, 95.58% and 94.22%,respectively.The Kappa test was performed on both methods, K=0.872 (P® MTBDRplus VER2.0 kit had high sensitivity and specificity for detecting MTBC in sputum, and it has good application value for early diagnosis of tuberculosis.
