摘要:

目的 比较多重荧光定量聚合酶链反应(PCR)和TaqMan微流体芯片(TAC)技术检测呼吸道病原体的效能。方法 收集419例急性呼吸道感染患者临床样本,分别采用TAC技术和多重荧光定量PCR进行多种呼吸道病毒核酸检测,比较2种方法的敏感性和特异性。结果 多重荧光定量PCR多种呼吸道病毒的阳性检出率为30.1%,敏感性为93.4%,特异性为98.9%;TAC技术多种呼吸道病毒阳性检出率为27.9%,敏感性为87.4%,特异性为98.9%。2种方法检测结果的一致性为92.8%,且敏感性和特异性差异均无统计学意义(P>0.05)。结论 TAC技术与多重荧光定量PCR检测常见呼吸道病毒的敏感性和特异性相近,但TAC技术检测病原谱范围更广,在紧急情况下可作为快速筛查多种呼吸道病原体的有效方法。

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.
