PCR vs. Rapid Antigen Testing: What It Means for Isolation and Patient Care

Does a faster test always lead to a better decision? In this episode of The Infection Control Exchange, recorded at IPAC GTA Education Day, host Wayne Tucker explores rapid antigen testing versus PCR for influenza A, influenza B and COVID-19. The conversation focuses on practical questions healthcare teams face: how reliable the result is, how quickly staff can act on it, and what it means for patient or resident precautions. Topics include: • The differences between rapid antigen and molecular PCR testing. • Strengths and limitations of each approach. • Negative antigen results and the risk of false reassurance. • How faster multiplex PCR can support clinical and IPAC decisions. • Implications for isolation, cohorting, patient placement and outbreak response. • Testing considerations in hospitals, long-term care, ambulatory care, and rural settings. • Costs, workflow, repeat testing and potential duplication. As rapid PCR becomes more accessible, should healthcare organizations reconsider where rapid antigen testing fits? Hosted by Wayne Tucker, BA, MSc (Psych), EMBA, MSc (IPAC), CIC, LTC-CIP.
