Of 145 mycobacterial isolates tested, comprising 89 MTBC and 56 non-tuberculous mycobacteria (NTM), BD ProbeTec ET correctly identified 87 MTBC and 56 NTM but missed two MTBC. Three NTM were misidentified when NAP was incubated at 37 °C only. Overall sensitivity, specificity and positive and negative predictive values were respectively 97.8, 100, 100 and 96.6 % for the BD ProbeTec ET system and 100, 94.6, 96.7 and 94.6 % for NAP. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/jmm.0.05454-0
