Details
The gut microbiome plays a critical role in mediating the effects of diet, digestion, immunity, metabolic function, and more. The GI-MAP (Microbial Assay Plus) test is truly unique in the field – relying exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more by targeting their specific DNA, providing quantitative insights to guide more personalized treatment protocols. StoolOMX is a powerful GI-MAP add-on test that evaluates 25 bile acids (total concentrations, percentages, and ratios) and 9 short-chain fatty acids (SCFAs), offering clinicians valuable insights into gut functionality and conditions such as IBS, IBD, bile acid diarrhea, and altered gut motility. By ordering StoolOMX alongside the GI-MAP, practitioners can uncover the underlying causes of these common conditions.

Optimal Health — It All Starts with the GI-MAP™
Research overwhelmingly indicates that gut health impacts overall health. The gut microbiome, in particular, plays a critical role in mediating the effects of diet and other factors on health, including digestive, immune, metabolic, and neuroendocrine functions. Assessing GI health with the proper tools can help practitioners get to the root cause of chronic illness. The GI‑MAP (Microbial Assay Plus) is unique in the field of comprehensive stool testing. It relies exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more, by targeting the specific DNA of the organisms tested.
With the StoolOMX add-on to the GI‑MAP, practitioners can:
- Evaluate bile acid metabolism and its impact on fat digestion, microbiome health, and gut motility.
- Assess SCFA production, which reflects dietary microbial fermentation, inflammatory balance, and gut lining integrity.
- Gain actionable insights to design personalized treatment plans targeting gut optimization.
When combined with the GI‑MAP, StoolOMX provides an unparalleled view into the root causes of gut dysfunction, helping to improve outcomes for patients experiencing digestive and systemic symptoms.
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 who rely on the efficacy of the GI-MAP. To achieve it, Diagnostic Solutions performs rigorous quality control and has validated all molecular target quantification assays to meet or exceed FDA standards.
GI-MAP Allows for Personalized Treatment Plans and Informative Retests
The GI-MAP's accuracy and reliability allow 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.
