Abstract

The automated GenoType MTBC assay was evaluated for the ability to detect and identify members of the Mycobacterium tuberculosis complex. In addition to 35 reference strains and 157 clinical isolates, performance of this assay was tested directly on 79 smear-positive clinical specimens. The assay proved as accurate as the reference deletion analysis for all 192 isolates and detected and identified M. tuberculosis complex members in 93.2% of the specimens containing the M. tuberculosis complex.
