GI-MAP – GI Microbial Assay Plus
The GI-MAP® (Microbial Assay Plus) is a comprehensive stool test that relies on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, H. pylori, fungi, and more by targeting the specific DNA of the organisms tested.
New for 2025 – Bile Acids and Short Chain Fatty Acids Testing
Introducing the StoolOMX™ Add‑on Panel for GI‑MAP – The new StoolOMX add-on measures 25 bile acids as well as 9 short chain and branch chain fatty acids (SCFAs) — microbial metabolites essential for gut health. SCFAs reflect microbial activity, fiber fermentation, and gut barrier integrity, while bile acid levels provide insights into malabsorption, bile acid diarrhea, and dysbiosis.
Additionally, recent studies show that up to 30% of patients with IBS‑D are affected by bile acid diarrhea, underscoring the importance of evaluating bile acids in clinical practice.
The markers on StoolOMX provide another layer of insight into your patient's gut health, allowing you to create more precise treatment plans that improve patient outcomes. Add StoolOMX to the GI‑MAP for a truly comprehensive view of gut health for optimized wellness.
Optimal Health — It All Starts with the GI‑MAP
Research overwhelmingly indicates that gut health impacts overall health. The gut microbiome plays a critical role in mediating the effects of diet and other factors on digestive, immune, metabolic, skin, brain, and neuroendocrine health. Results allow practitioners to personalize gut healing protocols that optimize overall health. Get to the root cause of chronic conditions for your patients with GI‑MAP.

Results You Can Rely On
Why Is Quantification Using qPCR Technology So Important?
Unlike other comprehensive stool tests on the market, the GI-MAP can provide practitioners with truly quantitative results. qPCR offers a much more accurate way to detect and quantify clinically-relevant organisms than standard PCR, culture, microscopy, or DNA sequencing-based methods. Accurately assessing how much of an organism's DNA is present in a patient's stool sample is essential for helping practitioners to determine the clinical significance of pathogenic organisms and dysbiosis patterns.
qPCR's Reliability, Reproducibility, and Use in Clinical Research
Although qPCR is becoming more commonplace in in-vitro diagnostics (IVD), we are the only laboratory in the United States exclusively using qPCR technology for advanced comprehensive stool testing. This technology is used routinely in clinical and academic research because it provides highly-accurate quantification, as well as high levels of sensitivity and specificity. Standard PCR technology doesn't offer the same level of sensitivity, or the ability to express precise numerical results.
The GI-MAP also provides consistently reproducible results. Reproducibility is of crucial importance to the practitioners and patients that rely on the efficacy of the GI-MAP. To achieve it, we perform rigorous quality control, and have validated all molecular target quantification assays to meet or exceed FDA standards.
GI-MAP Allows for the Personalized Treatment Plans and Informative Retests
The GI-MAP's accuracy and reliability allows practitioners to create personalized treatment protocols to address gut dysfunction based on which infections are urgent, which areas of the gut are already optimized, and which areas should be addressed after an infection is resolved.
Additionally, the quantification offers a remarkable ability to see how treatment modalities are working because a retest after treatment can show whether a parasite has resolved, dysbiosis has improved, and more.
Methodology
Quantitative PCR (qPCR) or Real-Time Polymerase Chain Reaction (RT-PCR) – Provides you with true quantitative values. It helps differentiate trace levels of an organism from frank elevations indicative of active infection.
Specimen Requirements
Single Stool Sample – Ambient room temperature in specimen vial provided.
