Abstract excerpt
The GenoType CMdirect Ver 1.0 and GenoType Mycobacterium Common Mycobacteria Ver 2.0-line probe assays were utilized to identify nontuberculous mycobacteria (NTM) from decontaminated sputum in a GeneXpert MTB/RIF Ultra negative cohort. A preliminary NTM prevalence of 1.7 % was observed, with a 100 % specificity. The high specificity advocates the CMdirect as a possible rule-in test for NTM disease.
