WebMultiplex PCR is considered as a rapid and sensitive technique for the detection of respiratory viruses. Therefore, we evaluated the performance of the TaqMan SARS-CoV-2, Flu A/B, RSV RT-PCR multiplex assay for the detection and differentiation of SARS-CoV-2, RSV, and Flu A and B from the nasopharyngeal swabs and saliva. WebThe Xpert assay showed higher sensitivity for FluA (100% vs. 89.8%) and FluB detection (100% vs. 95.3%), and also higher accuracy (98.9% vs. 95.7%) for FluA than the CDFA-PCR. The positive and negative predictive values (NPV) for the three viruses ranged from 90.5% to 100% in the two assays, with higher NPV for FluA and FluB in Xpert assay.
