- K121894: Xtag Gastrointestinal Pathogen Panel (GPP) Xtag Data Analysis Software for GPP (Tdas GPP) Luminex Magpix, Luminex Molecular Diagnostics, Inc. (2013) Summary page 6.
- DEN130003: Xtag Gastrointestinal Pathogen Panel (GPP) Xtag Data Analysis Software for GPP (Tdas), Luminex Molecular Diagnostics, Inc. (2013). Our reading of the summary gave K121454, which is not in FDA’s 510(k) list. The device the summary names is FDA’s De Novo DEN130003, Xtag Gastrointestinal Pathogen Panel (GPP) Xtag Data… (Luminex Molecular Diagnostics, Inc.), granted Jan 14, 2013; older De Novo requests were first filed under a 510(k) number, so this links to the grant.

## Indications for use
The Verigene Enteric Pathogens Nucleic Acid Test (EP) is a multiplexed, qualitative test for simultaneous detection and identification of common pathogenic enteric bacteria, viruses and genetic virulence markers from liquid or soft stool preserved in Cary-Blair medium, collected from individuals with signs and symptoms of gastrointestinal infection. The test is performed on the automated Nanosphere Verigene System utilizing reverse transcription (RT), polymerase chain reaction (PCR), and array hybridization to detect specific gastrointestinal microbial nucleic acid gene sequences associated with the following pathogenic bacteria and viruses: • Campylobacter Group (composed of C. coli, C. jejuni, and C. lari) • Salmonella species • Shigella species (including S. dysenteriae, S. boydii, S. sonnei, and S. flexneri) • Vibrio Group (composed of V. cholerae and V. parahaemolyticus) • Yersinia enterocolitica • Norovirus GI/GII • Rotavirus A In addition, EP detects the Shiga toxin 1 gene and Shiga toxin 2 gene virulence markers. Shiga toxin producing E. coli (STEC) typically harbor one or both genes that encode for Shiga Toxins 1 and 2. EP is indicated as an aid in the diagnosis of specific agents of gastrointestinal illness, in conjunction with other clinical, laboratory, and epidemiological information; however, is not to be used to monitor these infections. EP also aids in the detection and identification of acute gastroenteritis in the context of outbreaks. Due to the limited number of positive specimens collected for certain organisms during the prospective clinical study, performance characteristics for Yersinia enterocolitica, Vibrio Group and Shigella species were primarily established with contrived specimens. Concomitant culture is necessary for organism recovery and further typing of bacterial agents. EP results should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. Confirmed positive results do not rule out co-infection with other organisms that are not detected by this test, and may not be the sole or definitive cause of patient illness. Negative EP results in the setting of clinical illness compatible with gastroenteritis may be due to infection by pathogens that are not detected by this test or non-infectious causes such as ulcerative colitis, irritable bowel syndrome, or Crohn’s disease.
