xTAG® Gastrointestinal Pathogen Panel (xTAG GPP)

Globally, there are an estimated two billion cases of diarrheal symptoms every year. Due to similar symptoms virus, parasite and bacteria, a comprehensive diagnostic is difficult. xTAG GPP is a qualitative multiplex diarrhea test that helps molecular biologists and microbiologists with the simultaneous detection and identification of gastrointestinal pathogens. The assay uses Luminex xTAG Technology and the xMAP® Technology platform detect multiple infectious agents in a single sample.

Transforming diarrhea diagnostics

xTAG GPP is the first GI diagnostic to offer 15 major infectious organisms in a single test. It can detect Hospital Acquired Infections (HAI) such as C. difficile or Norovirus, foodborne illness agents like E. Coli or Salmonella and common pediatric diarrhea.

*Due to low sample size, clinical sensitivity was not assessed for ETEC, Yersinia enterocolitica and Vibrio cholerae. However, analytical accuracy for these analytes was demonstrated in the limit of detection and reactivity studies with cultural isolates or plasmids.
