GI Map Test + Fecal Gluten Peptide

Here's the part nobody warns you about when you go gluten-free.

You read every label. You ask the server twice. You bring your own snacks to the office party. You skip the wedding cake. And six months in, your gut is still running the same script — the bloating, the fog, the unpredictable mornings, the dinner you left early.

So you start asking the only question that's left: am I doing this wrong, or is something else going on?

This test was built for that exact question. One stool sample. Two answers. Let's take them in order.

What the GI-MAP actually is

The GI-MAP is a stool test that looks at the DNA of the organisms living in your gut. Not their leftovers. Not their proteins. Their actual genetic code.

That sounds like a small distinction. It isn't. It's the whole game.

Older stool tests rely on culturing — growing organisms in a dish to count them. The problem is that most of the organisms in your gut don't grow well in a dish. They evolved to live in a low-oxygen, body-temperature, nutrient-rich environment. Stick them on a petri dish and most of them die quietly without leaving a trace. Which means older stool tests systematically miss most of what's actually living in you.

The GI-MAP doesn't culture anything. It uses qPCR — quantitative polymerase chain reaction — to find each organism's unique DNA signature and count exactly how much of it is there. qPCR is the same technology used in research labs to track viral load, identify bacterial outbreaks, and confirm pathogens in clinical samples. It's accurate, reproducible, and — most importantly — quantitative.

Quantitative is the word that does the heavy lifting. The report doesn't just say "Klebsiella present." It tells you how much Klebsiella, against a reference range. Numbers can be compared. Numbers can be tracked over time. Numbers tell your practitioner which patterns deserve attention now and which can wait.

What the report actually shows you

Sixty-five markers across nine categories, every one of them quantified:

Bacterial pathogens (12 markers). The big-name organisms most people think of when they hear "stool test." Things like Salmonella, Shigella, the toxic strains of E. coli, C. difficile and its toxins, Campylobacter, Yersinia. If any of these are showing up in measurable quantities, your practitioner needs to know — and so do you.

Viral pathogens (4 markers). Norovirus GI and GII, Adenovirus 40/41, Rotavirus A. Most stool tests skip viruses entirely. The GI-MAP catches them.

Parasitic pathogens (3 markers). Cryptosporidium, Entamoeba histolytica, Giardia. The classic gut parasites that food diaries and elimination protocols have no way of catching.

H. pylori — and its virulence factors (3 markers). Helicobacter pylori is a bacterium that lives in the stomach and upper GI tract of a huge percentage of the population. Most of the time it's silent. Sometimes it's not. The GI-MAP doesn't just tell you whether H. pylori is present — it tests for cagA and vacA, the two virulence factors that distinguish the strains worth paying attention to from the ones that probably aren't doing much. That's the kind of nuance older tests can't give you.

Normal gut bacteria (9 markers). This is where most tests fall apart. The GI-MAP measures the good guys — Bacteroides fragilis, Bifidobacterium, Lactobacillus, Akkermansia muciniphila, Faecalibacterium prausnitzii, Roseburia, and others. Why does this matter? Because telling you what's wrong is half the picture. The other half is whether the beneficial half of your microbiome is still showing up to do its job. If your Akkermansia is low, that's information. If your Faecalibacterium is in the basement, that's information. You can't build a smart plan without it.

Opportunistic bacteria. Citrobacter, Klebsiella, Proteus, Pseudomonas, Staphylococcus, Streptococcus, Methanobacteriaceae, Morganella, and others. These aren't classic pathogens — they're organisms that live quietly in healthy guts and start acting up when the microbial balance shifts. The "opportunistic" panel is also where some of the markers most associated with autoimmune patterning live. This is the part of the report your practitioner will spend the most time on.

Fungi and yeast. Candida albicans, other Candida species, Geotrichum, Microsporidia, Rhodotorula. If you've spent any time on the gut-health internet, you know that "candida" gets thrown around carelessly. The GI-MAP gives you an actual measurement instead of a guess.

Intestinal health markers. This is the section most practitioners flip to first:

• Calprotectin — an inflammation marker. When it's elevated, the gut lining is inflamed.
• Secretory IgA (sIgA) — your gut's first line of immune defense. High and low both tell a story.
• Anti-gliadin IgA — an immune response to gluten in the gut.
• Elastase-1 — a measure of pancreatic enzyme output. Low elastase means food isn't getting broken down properly upstream.
• Steatocrit — fat in the stool. A marker of malabsorption.
• Beta-glucuronidase — a marker linked to hormone recycling and detoxification.
• Occult blood — hidden blood in the stool.

These seven markers turn the GI-MAP from a microbiome map into something much more useful: a picture of how the whole digestive system is functioning, not just who lives in it.

Antibiotic resistance genes. A targeted panel of resistance markers across major antibiotic classes. If antibiotic decisions are on the table — for H. pylori, for an opportunistic bacterial overgrowth, for anything — knowing which resistance genes are already present in your gut is the difference between a smart decision and a wasted course.

And then the new generation marker: the Fecal Gluten Peptide

Here's where the new generation panel earns its name. The Fecal Gluten Peptide assay measures the 33-mer gliadin peptide directly in your stool.

The 33-mer is the specific fragment of gluten that resists human digestion. Your enzymes can't fully break it down. So if you ate gluten in the last two to four days — even a hidden trace, even from a contaminated kitchen, even from the "gluten-free" oats that got milled on a shared line — that 33-mer fragment makes it through your digestive tract and ends up in your stool. The assay sees it.

No food diary. No memory test. No "I think I was careful at brunch." Just a direct molecular reading of whether gluten reached you.

That 2–4 day window is the whole point. Long enough to catch hidden exposure from a weekend out. Short enough to be actually useful. It's the difference between wondering and knowing.

Bottom line

One stool sample. 66 markers. The full GI-MAP plus the new Fecal Gluten Peptide layer. A consolidated written report your practitioner can read clinically — and, if you want it, an expert review video walking you through what's in it.

THIS TEST IS FOR YOU, IF

You Already Know Your Own Story. This Is For The Moments In It.

The wedding. The work trip. The dinner with the in-laws. The week you swore was clean.

• You manage celiac disease or gluten sensitivity, and you've stopped trusting menus
• You've been gluten-free for months and your symptoms still come without warning
• You travel for work and need to know whether your hotel breakfasts are quietly costing you
• You share a kitchen with people who eat gluten and you've wondered about the toaster, the cutting board, the wooden spoon, the colander, the butter dish
• You've cancelled plans, left dinners early, or quietly avoided situations without wanting to explain why
• You're tired of the friend who says "a little won't hurt," and the part of you that wishes they were right
• You've spent years collecting opinions and you'd like, finally, to collect a number
• You want one piece of evidence that settles the argument with yourself
