Abstract:

Objective To compare the efficiency of multiplex fluorescence quantitation polymerase chain reaction(PCR) and TaqMan array card(TAC)for determining multiple respiratory pathogens. Methods The clinical respiratory specimens were collected,and the nucleic acid was determined by multiplex fluorescence quantitation PCR and TAC. The sensitivities and specificities of the 2 methods were compared. Results The positive rate,sensitivity and specificity of multiplex fluorescence quantitation PCR were 30.1%,93.4% and 98.9%. The positive rate,sensitivity and specificity of TAC were 27.9%,87.4% and 98.9%. The consistency of the 2 methods was 92.8%,and there was no statistical significance in the sensitivities and specificities of the 2 methods(P>0.05). Conclusions The sensitivities and specificities of the 2 methods are close. The spectrum of respiratory pathogens determined by TAC is broader,and it can be used as an efficient method for rapid screening of multiple respiratory pathogens in emergency circumstances.
