"xTAG® GPP is a qualitative molecular multiplex test intended for the simultaneous detection and identification of multiple gastrointestinal pathogens including bacteria, viruses, and parasites. The assay uses the proprietary Luminex xTAG® Technology and the xMAP® Technology platform to detect multiple targets in a single sample. xTAG GPP can detect agents that can cause Hospital Acquired Infections (HAI) such as C. difficile or norovirus, foodborne illness agents like E. coli or Salmonella, and common causes of diarrhea in infants and in children 5 years old and younger, such as rotavirus A, Campylobacter, and Shigella."
