Two reports, one sample

Which test do I need?

CGI — Core Gut Insights looks at the gut itself. CMA — Complete Microbiome Assessment includes everything in CGI and adds how the gut connects to the rest of the body. Same kit, same laboratory, same way of reading it.

The key difference

One question each report is built to answer.

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?”

Whichever you choose

The same kit, the same care, behind both

What customers and the practitioners they work with say — and the practical details that apply to either report.

GutID revealed my FODMAP sensitivity and probiotic needs, giving my clinician the insight to provide precise advice that keeps my gut feeling great.

Penelope K.

For years, I struggled with health issues, including persistent acne, only to be told that all standard tests were normal. But I knew something wasn't right. It wasn't until my physician recommended GutID that I finally found answers. GutID has been absolutely instrumental in my health journey, providing insights I couldn't find elsewhere.

Lindsey C.

GutID helped my nutritionist find the right probiotics and supplements to ease my years of stomach issues.

Denise S.

GutID helped me realize how important gut health is - now I can enjoy the foods I love while avoiding what irritates my gut.
