Gastrointestinal
A single stool collection analyzed four ways, from the comprehensive Total GI profile to the focused, first-line EGHA assessment.

A partner in precision medicine.
Molecular diagnostics, microbiology, and functional biomarkers reported together, so complex cases read as one clinical picture rather than a stack of disconnected results.
Test Categories
Specialty testing organized by clinical area, from comprehensive gut and gastrointestinal profiles to culture-based nasal and throat evaluation.
Nasal & Throat
Culture-based upper respiratory testing of the nasal passages and throat, with MARCoNS evaluation and susceptibility testing on clinically significant isolates.
- Upper Respiratory Micro Screen (Nasal & Throat)
- Bacterial & Fungal Culture
- MARCoNS Evaluation
- Antimicrobial Susceptibility & Natural Agent Sensitivity

One stool collection. Four methods. One report.
Infection, dysbiosis, inflammation, immune activity, and absorption are evaluated side by side, so the findings can be weighed against one another instead of read in isolation.
PCR and culture, not one or the other
Multiplex PCR detects targets at the genetic level. Culture shows which organisms are viable, adding context that helps separate clinically relevant findings from incidental molecular detections.
Coverage across methods
Viral, bacterial, fungal, and parasitic targets are addressed across methods, with direct microscopy used to identify cysts, eggs, and larvae that molecular testing can overlook.
Sensitivity data you can prescribe from
Positive bacterial and fungal cultures carry antibiotic susceptibility plus sensitivity against a panel of natural agents, giving integrative providers a fuller set of options.
Total GI vs the competition
Broader pathogen detection, culture-confirmed sensitivity, and a deeper functional marker menu. See how Total GI measures up against the GI panels providers most often compare it to.

We advance precision medicine with diagnostics built to be clinically meaningful, helping providers catch disease earlier, tailor treatment, and follow patients toward better outcomes.
Built for clinical decisions
Testing and reporting designed around what you need to decide, not just what is detectable.
Integrated interpretation
Findings read in relationship to one another, so meaningful patterns are not lost in isolated results.
Actionable insight
Results oriented toward your next step, helping identify the underlying drivers of dysfunction.
Responsible stewardship
Richer clinical context helps separate what genuinely warrants treatment from what does not.
Built for longitudinal care
Consistent methodology for repeat testing, treatment monitoring, and adjustment over time.
Depth a practice can afford to repeat
Specialty-grade testing priced so ongoing monitoring stays realistic for your practice, not just the first order.
Why RSM as your laboratory partner
