The BioFire-Respiratory Panel 2.1 is a comprehensive, multiplex PCR-based diagnostic test that simultaneously detects and identifies 22 common respiratory pathogens—including SARS-CoV-2, influenza A/B, RSV, rhinovirus/enterovirus, adenovirus and several bacteria—from a single nasopharyngeal swab sample. The panel offers rapid, accurate and actionable insights for clinicians to differentiate between viral and bacterial infections.
