Testing for Influenza

You don’t need a flu test to diagnose the flu! But there are situations where rapid antigen testing or PCR is valuable. Listen to this episode of PEM Currents, the Pediatric Emergency Medicine podcast, to learn more about the test characteristics of common assays and when to obtain testing when prevalence rates for the flu are high.
