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. WebA RT-PCR test called the Flu SC2 Multiplex Assay can detect any of three viruses at the same time: the COVID-19 virus, influenza A and influenza B (flu). Only a single sample is needed to check for all three viruses. This could be helpful during the flu season. But a negative result does not rule out the possibility of any of these infections.
