What this test measures
The GI Pathogen Panel is a multiplexed nucleic acid test intended for the simultaneous qualitative detection and identification of nucleic acids from multiple bacteria, viruses and parasites directly from stool samples obtained from individuals with gastrointestinal symptoms. This comprehensive panel detects the genetic material (DNA or RNA) of 15 common pathogens that can cause diarrhea, abdominal pain, nausea, vomiting, and other digestive symptoms.
The GI pathogen panel detects the genetic material (RNA or DNA) of some of the more common pathogens. It can identify co-infections (more than one microbe causing infection) and identify microbes that might be missed with traditional testing. Results of a GI pathogen panel may be available within a few hours, compared to a few days with some traditional testing. Unlike traditional stool culture methods that may take several days and only detect certain types of bacteria, this modern molecular testing approach provides rapid, comprehensive results that can help healthcare providers determine the specific cause of gastrointestinal illness.
What's included
Who should consider this test
You might consider this test if you are experiencing any of the following:
- Individuals experiencing persistent diarrhea lasting more than a few days, especially when accompanied by fever, abdominal cramping, or blood in stool.
- Those with recent travel history who develop gastrointestinal symptoms, as travel-related infections may be caused by pathogens not commonly found in their home region.
- Patients with severe dehydration or concerning symptoms that require rapid identification of the causative pathogen to guide appropriate treatment decisions.
- Immunocompromised individuals who are at higher risk for severe complications from gastrointestinal infections and may require prompt diagnosis and treatment.
- People who have been exposed to potential sources of contamination, such as contaminated food or water, or during outbreaks in communal settings like nursing homes or daycare centers.
- Healthcare workers or food handlers who need to confirm they are free of infectious pathogens before returning to work in environments where transmission risk is high.
What to expect
Preparation
No special preparation is required for this test. Individuals should collect a fresh stool sample and avoid contaminating it with urine or water.
Sample Type
A small amount of fresh stool is collected in a special transport container provided by the laboratory. The sample should be collected within 2 hours or preserved in the provided transport medium.
Collection
The stool sample can typically be collected at home and transported to a laboratory location. No doctor visit is required for sample collection, making the process convenient and accessible.
Turnaround
Results are typically available within 1-3 business days, which is significantly faster than traditional stool culture methods that may take 3-5 days or longer.
Understanding your results
Results are reported as qualitative (Positive, Not Detected) for each pathogen tested. A positive result indicates that the genetic material from a specific pathogen was detected in the stool sample, while a negative result means that particular pathogen was not found.
| Population | Reference Range | Notes |
|---|---|---|
| All ages | Not Detected | Normal result indicates no pathogenic organisms were detected in the stool sample |
Reference ranges may vary by laboratory and individual factors. Results should be interpreted by a healthcare provider in the context of your overall health.
What does a “Low” result mean?
A negative result means that the microbes tested were not detected and the person's signs and symptoms may be caused by a condition other than an infection or a pathogen that was not tested for. Microbes are shed into the stool intermittently. A negative result may mean that the microbe causing the person's infection was not present in the stool at the time the sample was collected. A negative result should not rule out infection in patients with a high pretest probability for gastrointestinal infection. The assay does not test for all potential infectious agents of diarrheal disease.
What does a “High” result mean?
A positive result for any pathogen indicates the presence of that specific microorganism in the stool sample and may suggest it is contributing to gastrointestinal symptoms. Multiplex GPPs consistently detect multiple targets more frequently than conventional testing. One study of 709 samples found multiple pathogens in 16.4% of samples using the BioFire GIP versus 1% after conventional testing. The detection of multiple pathogens does not necessarily mean all are causing illness, as some individuals may carry certain organisms without symptoms.
Privacy & confidentiality
Your GI pathogen panel results are completely confidential and protected under HIPAA privacy regulations. Results are not shared with your personal physician unless you specifically request it, will not be added to your medical records, and will not appear on insurance explanation of benefits statements since this is direct-pay testing.
