What this test reveals
What this test reveals
The GI-MAP (Gastrointestinal Microbial Assay Plus) uses quantitative PCR technology to detect parasites, bacteria, fungi, and viruses in your gut with unmatched precision — plus critical markers for inflammation, immune function, and intestinal permeability.
Unlike culture-based stool tests that miss over 80% of gut organisms, PCR technology detects DNA directly, identifying pathogens and imbalances that conventional gastroenterology testing simply cannot find. This is why functional medicine practitioners consider GI-MAP the gold standard for gut assessment.
People usually reach for this kind of diagnostic when they want a clearer read on pathogenic bacteria (h. pylori, c. difficile, etc.), parasites (giardia, cryptosporidium, worms), opportunistic bacteria and fungal overgrowth (candida), especially when symptoms or prior testing still leave blind spots.
Once results are back, you can upload them into Gabriel to connect the findings to symptoms, protocols, and next-step testing instead of leaving them as a static report.
Commonly relevant for: Gut Issues Ibs Sibo Leaky Gut, Autoimmune Disorders, Skin Conditions Eczema Psoriasis.
Gabriel difference
Why this becomes more useful inside Gabriel
The gut is the seat of health — 70% of your immune system lives there. Conventional stool tests are shockingly inadequate, missing most pathogens and telling you nothing about intestinal permeability or immune function. GI-MAP reveals the complete gut ecosystem: the good, the bad, and the ugly. Gabriel uses GI-MAP data to design targeted antimicrobial protocols, probiotic strategies, and gut-healing programs that address root causes rather than just suppressing symptoms.
Gabriel interprets results through a functional, root-cause lens: optimal ranges, pattern recognition across multiple diagnostics, and what the findings actually mean for action rather than just classification.
That means this test can feed directly into protocols, practitioner matching, food strategy, and follow-up testing instead of ending as a one-off PDF or lab portal result.

Frequently asked questions
Questions people usually ask before ordering
GI-MAP uses DNA-based PCR technology to identify and quantify bacteria, parasites, fungi, viruses, and digestive markers in a single stool sample. Unlike standard stool cultures that only grow a fraction of gut organisms, PCR detects DNA directly, providing a comprehensive map of your gut microbiome.
Standard stool tests use microscopy or culture methods that miss many organisms. GI-MAP uses quantitative PCR, meaning it not only detects pathogens but tells you exactly how much is present. This quantification helps practitioners determine clinical significance and track treatment effectiveness over time.
You collect a small stool sample at home using the provided kit, which includes a collection container and instructions. The sample is shipped to the lab in a prepaid mailer. No special diet preparation is required, though your practitioner may advise stopping certain supplements briefly before collection.
GI-MAP has high sensitivity (around 80%) for detecting pathogens via PCR. However, one peer-reviewed study noted specificity of only 26%, meaning false positives can occur. This is why practitioner interpretation is essential. Results should be correlated with symptoms, not treated in isolation.
Typically 10-14 business days from when the lab receives your sample. Results are sent to your ordering practitioner with detailed reference ranges and clinical significance markers.
The GI-MAP costs approximately $350-400 through most practitioners. Some offer bundled pricing with consultations. Insurance rarely covers functional stool testing, though HSA/FSA funds can usually be applied.
