摘要: The large and growing number of viral bacterial pathogens responsible for respiratory infections poses a challenge laboratories seeking to provide rapid comprehensive pathogen identification. We evaluated novel application the TaqMan low-density array (TLDA) cards real-time PCR detection 21 respiratory-pathogen targets. performance TLDA was compared that individual (IRTP) assays with same primers probes using (i) nucleic acids extracted from strains 66 closely related viruses bacteria (ii) 292 clinical specimens. With spiked samples, were about 10-fold less sensitive than IRTP assays. By specimens generate 2,238 paired assays, card exhibited 89% sensitivity (95% confidence interval [CI], 86 92%; range per target, 47 100%) 98% specificity CI, 97 99%; 85 overall as gold standard threshold cycle (CT) cutoff 43. approach offers promise simultaneous identification multiple outbreak investigations disease surveillance.
