Evaluation of BioCode GPP for Gastrointestinal Pathogen Detection

This technical report presents the findings of a multicenter evaluation of the BioCode Gastrointestinal Pathogen Panel (BioCode GPP) for the syndromic molecular detection of gastrointestinal pathogens from stool specimens. The study was conducted to compare the effectiveness of BioCode GPP against traditional microbiological detection methods, which are often limited in sensitivity and speed. A total of 1,558 stool samples were analyzed for 17 common bacterial, viral, and protozoan pathogens. The results indicated that BioCode GPP identified 392 positive samples, significantly higher than the 283 positives found using reference methods, demonstrating a notable increase in detection rates. The BioCode GPP exhibited high sensitivity and specificity, with overall values of 96.1% and 99.7%, respectively. This report outlines the methodology, results, and implications of using multiplex molecular panels for rapid pathogen detection, particularly in vulnerable populations at risk of acute gastroenteritis.
