NEW YORK (GenomeWeb) – A large, prospective study of pediatric gastroenteritis patients in Canada recently discovered higher-than-expected false-positive and false-negative results for Salmonella spp. in the Luminex xTAG Gastrointestinal Pathogen Panel (GPP) multiplex molecular test, a problem that the company has since solved.
Luminex said it had discovered the problem independently, through customer complaints received prior to the study's publication, and recently issued a software adjustment to fix the problem.
