Evaluation of the GenoType Mycobacteria Direct assay for detection of Mycobacterium tuberculosis complex and four atypical mycobacterial species in clinical samples.
We evaluated GenoType Mycobacteria Direct (GTMD), a novel commercial assay based on nucleic acid sequence-based amplification technology, for the detection of Mycobacterium tuberculosis complex, M. avium, M. intracellulare, M. kansasii, and M. malmoense directly from clinical specimens. A total of 134 respiratory and extrapulmonary samples from 65 patients were processed. Sensitivity, specificity, positive predictive, and negative predictive values for GTMD were 92, 100, 100, and 77%, respectively. The GMTD technique is useful, reliable, and rapid when used during the normal routine of a clinical laboratory.
