Why GutID is different
qPCR looks for a fixed list of organisms, and a 16S-only test reads one short piece of DNA. Titan-1 reads one continuous ~2,500-base fragment, so each bacterium is identified and measured as part of the whole ecosystem, even when no species name exists.

GutIDTitan-1
Now availableGutID Pro · For professional use · US only
31 commensal and dysbiotic markers, plus eight lab panels you would usually order as separate tests: the GI panel, inflammation and digestion and H. pylori. All in every kit, from one collection, each result read beside the whole ecosystem on one report.
Ordered and interpreted by approved clinicians in the US, except New York State. Not sold to patients.
65markers on top of Titan-1, in every kit
Options: fecal leukocytes and one C. difficile test.
Working together
Some practices stock the test and hand it over in the room. Others send the patient to us and keep their time for the consultation. Either way, you earn on every kit.
Clinics and groups
Buy at wholesale, keep kits on the shelf, and give the patient the test before they leave.
Solo practitioners
Recommend a patient-paid test through the Clinician Portal, or use your referral link.
GutID is the only test I can recommend, because of the underlying technology.
Where it fits
Six reasons practitioners order it, each shown as it prints in the report.
A baseline for patients focused on healthy aging, to retest against.
Organisms associated with weight, glucose and liver health, on the Complete report.
Organisms associated with IBS, IBD, bloating and irregularity, alongside your usual workup.
Organisms associated with immune, skin and histamine pathways, on the Complete report.
Organisms associated with mood and cognition, on the Complete report.
How much antibiotic resistance the community carries, and how it shifts on retest.
The platform
qPCR asks whether a named organism is present. A 16S-only read estimates composition, usually to genus. Titan-1 uses strain-level data to identify each bacterium to species, and measures how much of the community it holds.
A single ~2,500-base fragment, made by a patented method, spanning the full 16S gene, the ITS and the start of 23S, read intact.
Our own platform assigns identity from the whole long read rather than matching short markers, improving detection of poorly represented organisms.
A single continuous read reduces fragmentation bias, so diversity, evenness and relative abundance are measured on one consistent target.
Region proportions are schematic.
What your patient receives
Both open with the Microbiome Score, ecosystem highlights and Target Plot, so you know where to start reading. In the US, GutID Pro offers everything in Titan-1, plus 65 more markers in every kit: a GI panel, inflammation and digestion markers and H. pylori.
CGI
Gut function and digestion.
CMA
Everything in Core, plus four more gut axes.

Clinically authored and fully referenced, with a six-step interpretation sequence.
Both real CMA reports, first test and after intervention, sent to you by email.
Three live modules, run with The Nutrition Health Collective: foundations, interpretation and protocol design.
A live session each month working through real cases together.

One de-identified case after a fiber recommendation (psyllium husk). By the third test the individual reported their IBS symptoms had resolved. Both Target Plots are shown exactly as they appear in the case’s reports. A single case; individual results vary.
