Intended Use
The xTAG® Gastrointestinal Pathogen Panel (GPP) is a multiplexed nucleic acid test intended for the simultaneous qualitative detection and identification of multiple viral, parasitic, and bacterial nucleic acids in human stool specimens from individuals with signs and symptoms of infectious colitis or gastroenteritis. The following pathogen types, subtypes and toxin genes are identified using the xTAG GPP: - Campylobacter (C. jejuni, C. coli and C. lari only) . - Clostridium difficile (C. difficile) toxin A/B ● - Cryptosporidium (C. parvum and C. hominis only) ● - Escherichia coli (E. coli) 0157 . - Enterotoxigenic Escherichia coli (ETEC) LT/ST ● - Giardia (G. lamblia only also known as G. intestinalis and G. duodenalis) - . Norovirus GI/GII - . Rotavirus A - Salmonella ● - Shiga-like Toxin producing E. coli (STEC) stx 1/stx 2 . - Shigella (S. boydii, S. sonnei, S. flexneri and S. dysenteriae) ● The detection and identification of specific gastrointestinal microbial nucleic acid from individuals exhibiting signs and symptoms of gastrointestinal infection aids in the diagnosis of gastrointestinal infection when used in conjunction with clinical evaluation, laboratory findings and epidemiological information. A gastrointestinal microorganism multiplex nucleic acid-based assay also aids in the detection and identification of acute gastroenteritis in the context of outbreaks. xTAG® GPP positive results are presumptive and must be confirmed by FDAcleared tests or other acceptable reference methods. The results of this test should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. Confirmed positive results do out rule out coinfection with other organisms that are not detected by this test, and may not be the sole or definitive cause of patient illness. Negative xTAG® Gastrointestinal Pathogen Panel 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. xTAG GPP is not intended to monitor or guide treatment for C. difficile infections. The xTAG GPP is indicated for use with the Luminex® MAGPIX® instrument.

The description focuses on a multiplexed nucleic acid test for pathogen detection and identification, with no mention of AI or ML in the intended use, device description, or other sections.

No

Explanation: This device is a diagnostic test designed for the detection and identification of pathogens, not for treating or preventing disease.

Yes

The text explicitly states that the device is "intended for the simultaneous qualitative detection and identification of multiple viral, parasitic, and bacterial nucleic acids in human stool specimens" and "aids in the diagnosis of gastrointestinal infection".

No

The device is a multiplexed nucleic acid test that analyzes stool specimens using a specific instrument (Luminex® MAGPIX®). This involves physical reagents, laboratory procedures, and hardware, making it a hardware-based diagnostic test, not a software-only device.

Based on the provided information, yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the test is for the "simultaneous qualitative detection and identification of multiple viral, parasitic, and bacterial nucleic acids in human stool specimens from individuals with signs and symptoms of infectious colitis or gastroenteritis." This is a classic description of an in vitro diagnostic test, as it analyzes a biological sample (stool) outside of the body to aid in the diagnosis of a disease.
  • Sample Type: The test uses "human stool specimens," which are biological samples collected from a patient.
  • Purpose: The purpose is to "aid in the diagnosis of gastrointestinal infection" and "aid in the detection and identification of acute gastroenteritis in the context of outbreaks." This directly aligns with the definition of an IVD, which is used to diagnose or detect diseases or conditions.
  • Clinical Context: The intended use mentions using the results "in conjunction with clinical evaluation, laboratory findings and epidemiological information," further indicating its role in a clinical diagnostic process.

The fact that it's a "multiplexed nucleic acid test" and uses a specific instrument (Luminex® MAGPIX®) are details about the technology used, but the core function and intended use clearly place it within the category of an In Vitro Diagnostic device.

  • Shigella (S. boydii, S. sonnei, S. flexneri and S. dysenteriae) ●

The detection and identification of specific gastrointestinal microbial nucleic acid from individuals exhibiting signs and symptoms of gastrointestinal infection aids in the diagnosis of gastrointestinal infection when used in conjunction with clinical evaluation, laboratory findings and epidemiological information. A gastrointestinal microorganism multiplex nucleic acid-based assay also aids in the detection and identification of acute gastroenteritis in the context of outbreaks.

xTAG® GPP positive results are presumptive and must be confirmed by FDAcleared tests or other acceptable reference methods.

The results of this test should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. Confirmed positive results do not rule out coinfection with other organisms that are not detected by this test, and may not be the sole or definitive cause of patient illness. Negative xTAG® Gastrointestinal Pathogen Panel 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.

xTAG GPP is not intended to monitor or guide treatment for C. difficile infections.

The xTAG GPP is indicated for use with the Luminex® MAGPIX® instrument.
