The Genesig SARS-CoV-2 Winterplex is a CE marked, in vitro diagnostic, real-time, reverse transcriptase PCR (RT-PCR) multiplex assay intended for the qualitative detection of nucleic acid from SARS-CoV-2 (ORF1ab and S gene targets), Influenza A (Flu A), Influenza B (Flu B) and Respiratory Syncytial Virus (RSVA and B) in nasopharyngeal swabs, oropharyngeal swabs and sputum specimens. This multiplex assay provides rapid screening of individuals suspected of SARS-CoV-2, Flu A, Flu B and RSV infections and aids the diagnosis of suspected disease in patients.
