The respiraScreen 1 real time RT-PCR Kit is a screening assay for the simultaneous detection of three groups of different respiratory viruses. The design allows the differentiation of Influenza Virus (Flu A, Flu B) and Respiratory Syncytial Virus (RSV A, RSV B) from the pandemic coronavirus SARS-CoV-2 (E gene and RdRP gene), extracted from biological specimens.
