CGI or CMA - which GutID test is right for you
Both GutID reports are built on the same high-resolution bacterial sequencing platform and the same ecosystem-based interpretation framework. They differ in how far beyond the gut they look.
The key difference
CGI asks: “What is the current state of the bacterial ecosystem?”
CMA asks: “How might the bacterial ecosystem influence key physiological systems through the gut-brain, gut-immune, gut-metabolism, gut-cardiovascular and gastrointestinal axes?”
CGI — Core Gut Insights
$399 · Free shipping · HSA/FSA eligible
A focused assessment of bacterial ecosystem health, and a clinically actionable overview of microbiome structure.
- Resilience and biodiversity
- Beneficial bacteria
- Gut systems bacterial groups
- Nutrient and dietary component metabolism
Identifies key areas for dietary, lifestyle and microbiome-supportive interventions. View Core Gut Insights.
CMA — Complete Microbiome Assessment
$599 · Free shipping · HSA/FSA eligible
Everything in CGI, plus an expanded assessment of microbiome–host interactions through the Gut Axes section, which appears in the CMA report only:
- Gut-Brain Axis
- Gut-Gastrointestinal Axis
- Gut-Metabolism Axis
- Gut-Heart Axis
- Gut-Immune Axis
Intended to support ecosystem-level interpretation in complex or multi-system presentations. View Complete Microbiome Assessment.
What the difference costs
CGI is $399. CMA is $599. Both are run from the same single stool sample, on the same sequencing platform, with the same turnaround — once the lab receives your sample and it passes quality control, processing typically takes 3–4 weeks. The difference in price is the Gut Axes section: how far past the gut itself the report reads.
Which one is right for you
Choose CGI when the question is the gut itself — digestion, bloating, irregularity or food sensitivity.
Choose CMA when the picture is multi-system — fatigue, mood, metabolic, cardiovascular or immune concerns alongside gut symptoms.
