Kogene PowerChek Multiplex Real-time PCR Kits Versus the BioFire FilmArray Gastrointestinal Panel: Roles of Crossing Point Values and Melting Curves in Interpreting the FilmArray Gastrointestinal Panel.

ABSTRACT:

Background

Various molecular methods are used to rapidly detect gastrointestinal pathogens, highlighting the importance of understanding the performance of the associated kits in detail. We comprehensively assessed the performance of Kogene PowerChek multiplex real-time PCR kits (PowerChek Bacterial/Viral Kits) with the FilmArray GI Panel.

Methods

Residual stool specimens (N=246), initially tested utilizing the FilmArray GI Panel (May 2023-Jan 2024), were reanalyzed using PowerChek Bacterial/Viral Kits. Discrepancies were resolved by performing additional molecular assays and reviewing culture results when available. True positives (TPs)/true negatives were defined by concordant results in at least two assays. We determined cycle threshold (Ct)/crossing point (Cp) distributi
