The SARS-Cov-2 & Influenza A/B Nucleic Acid Test is a multiplex real-time RT-PCR assay intended for simultaneous qualitative detection and differentiation of SARS-CoV-2, influenza A (IFA), and influenza B (IFB) virus RNA in upper or lower respiratory specimens (such as nasopharyngeal and oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate or nasal aspirate) collected from individuals suspected of respiratory viral infection consistent with SARS-CoV-2, IFA or IFB by their healthcare provider. Clinical signs and symptoms of respiratory viral infection due to SARS-CoV-2, IFA or IFB can be similar.
