Abstract: | We have developed a Real-Time PCR assay to detect M. tuberculosis using the iCycler iQ detection system by TaqMan assay directly on the clinical specimen. A total of 513 clinical samples were taken from patients with suspected tuberculosis and other patients that had an active mycobacterial infection, as well as patients with diagnosed tuberculosis who were receiving antitubercular therapy. The sensitivity and specificity of this assay, 10% and 100%, respectively, were compared to those of conventional microbiological methods. |
