Emergency Use Authorized—designed to detect and differentiate​

Because influenza and COVID-19 share symptoms, accurate testing is needed to distinguish one from the other. This Emergency Use Authorized (EUA) multiplex PCR test is specifically designed to detect and differentiate between multiple respiratory viruses as the ongoing COVID-19 pandemic overlaps with respiratory virus season. The test uses an assay design with two SARS-CoV-2 targets to compensate for emerging variants and mutations and help provide confidence in results.
