Floré Gastrointestinal Pathogen Test
Find out if you have an infection of your digestive tract due to bacteria, parasites, or viruses.
Who should take this test?

Those who are experiencing symptoms such as diarrhea, abdominal cramps, nausea and/or vomiting. If you have loose stool that contains blood or mucus, you should also take this test.

  • Get fast, comprehensive results: detect and identify >90% of the causative bacterial, viral and parasitic agents of gastroenteritis within 3 days validated stool sample.
  • Simplify your detection process: one test provides answers for 14 pathogens
  • Provides accurate data for better patient management and outbreak investigations

What is the Floré Gastrointestinal Pathogen Test?

The Floré Gastrointestinal Pathogen Test is a multiplexed nucleic acid test intended for the qualitative detection and identification of various pathogenic microbes that may cause gastroenteritis and infectious colitis.  

What happens if my results are positive for an infection?

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. Any non-infectious GI issues such as ulcerative colitis, irritable bowel syndrome, or Crohn’s disease are not detectable by this test and the Floré Gastrointestinal Pathogen Test will be negative on these samples.

The Process

Our clinical lab will send out the needed collection materials for processing of your sample. Once you return the sample, we will take it from there.


Collect and Send

It takes only five minutes.

Our test is a PCR based test utilizing the xMAP bead hybridization and detection technology that simultaneously detects multiple bacterial, viral and parasitic pathogens in a single test.


Review Results

Results will be uploaded to our portal and available for review by you and your provider.

You should take this test if you’re suffering from:

  • Chronic and constant abdominal pain
  • Constipation/Diarrhea
  • Mucus in stool
  • Gassiness or Bloating
  • Travelers’ diarrhea

What does this Test Detect:

  • Infectious gastroenteritis
  • Infectious colitis
  • Acute gastritis
  • Community outbreaks
  • Foodborne GI illnesses
  • Epidemics/Pandemics

How it Works

The Floré Gastrointestinal Pathogen Test (GPT) is a qualitative multiplex test that can simultaneously detect and identify multiple bacterial, viral, and parasitic gastrointestinal pathogens from individuals with signs and symptoms of infectious colitis or gastroenteritis. The Floré GPT detects the gastrointestinal pathogen types, subtypes and toxin genes described in the table. It includes a reverse transcription polymerase chain reaction (RT-PCR) with xTAG universal tag sorting system and a subsequent bead hybridization utilizing the xMAP Technology platform. This is an efficient technology that enables the analyzer to capture and detect specific analytes of all target pathogens from the single sample provided.

The Floré Gastrointestinal Pathogen Test (GPT) is done in a CLIA certified laboratory, Floré Laboratories. The GPT incorporates multiplex reverse-transcriptase PCR (RT-PCR) with the xTAG universal tag sorting system on the Luminex xMAP platform. Positive results are presumptive and must be confirmed by FDA cleared tests or other acceptable reference methods and do not rule out co-infection with other organisms that are not detected in this test. The results of this test should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. Negative 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. This Floré Gastrointestinal Pathogen Test is not intended to monitor or guide treatment for C. difficile infections. This test was validated and verified by Floré Laboratories to match the manufacturer's validation data. CLIA ID: 05D2194956
