  • a Prodesse assays were considered the gold standard for comparison. Viruses targeted by both FilmArray RP and Prodesse assays, but not detected during this study, were as follows: influenza A H1 seasonal virus, influenza A H3 seasonal virus, and parainfluenza virus 2. PRO, Prodesse; FA, FilmArray RP; PPV, positive predictive value; NPV, negative predictive value.
