Why this test

Why look at your gut, really

Most stool tests stop at one question — “is there a pathogen?”. GI-MAP plus Zonulin goes further: it reads the terrain. Permeability, inflammation, immune tone and how well you actually digest — the molecules that explain your symptoms, not just the bugs that don’t. That extra layer is usually where the answer is hiding.

What you'll discover

What GI-MAP reveals

A single stool sample, read by quantitative PCR, maps what is actually living in your gut — in measured amounts — and whether your gut wall is holding the line.

The real balance of your microbiome — beneficial, opportunistic and dysbiotic species, quantified
Hidden pathogens older tests miss: parasites, H. pylori with its virulence factors, fungi
Intestinal permeability — “leaky gut” — through the added zonulin marker
Digestion and absorption markers (pancreatic elastase, steatocrit)
Gut inflammation and immune activity (calprotectin, secretory IgA)
Antibiotic-resistance genes and opportunistic overgrowth signals

Read by people, not algorithms

Every result is reviewed twice over

A lab number on its own changes nothing. What matters is who reads it — and your results pass through two layers of expertise before they ever shape your protocol.

Alessandra Ginsburg

IFM-certified Functional Nutrition Practitioner

Alessandra interprets every marker against your full clinical picture — your symptoms, history, lifestyle and goals — not against a generic reference range. She is the one who turns raw lab data into the specific, personalised actions in your protocol, and who decides when a finding warrants medical evaluation and a referral to a physician.

Specialist functional-medicine laboratory · since 1997 · 100+ countries

Your sample is processed by Nordic Laboratories, a specialist functional-medicine lab operating since 1997 across more than 100 countries. Their scientific team runs the validated PCR and metabolomic assays under strict quality control, so the data Alessandra works from is accurate, reproducible and clinically meaningful.

Where we focus

Where this test looks

GI-MAP is not a single number — it reads four connected layers of gut health at once, which is why it so often becomes the unlock for symptoms that seem unrelated.

Image

Microbiome balance

Quantitative PCR measures beneficial commensals against opportunistic and dysbiotic species, so we see not just who is present but in what proportion.

Image

Pathogens & parasites

Sensitive enough to catch low-grade infections — parasites, H. pylori with virulence factors, fungal overgrowth — that older culture-based stool tests routinely miss.

Image

Barrier integrity

The zonulin marker quantifies intestinal permeability — the gateway condition behind “leaky gut” — telling us whether to repair the wall first or work the microbial side.

Image

Digestion & inflammation

Elastase, steatocrit, calprotectin and secretory IgA show how well you break food down and how much immune activity and inflammation your gut is carrying.

How this test can help

How GI-MAP helps

Because the gut sits upstream of so much, this one test reaches well beyond digestion. Here is where its findings most often change the plan.

Digestive health

BloatingIBSIrregular stoolsSIBO / SIFOReflux

Pinpoints which microbes to clear, which to feed, and whether the barrier needs repairing before anything else — the backbone of a gut protocol.

What's included

More than a test

A lab result you can’t act on is just paper. Every functional test at FunctionAlps comes wrapped in the analysis, the human explanation and the plan that turn it into change.

The test

A clinically validated functional lab test, with the collection kit sent to your door.

Specialist analysis

Your sample is processed by the laboratory and returned as a full functional report.

A results call with our nutritionist

Alessandra walks you through every finding in plain language — what it means, and what it doesn’t.

Your recommendations, in the report

Written, personalised recommendations tied directly to your results — yours to keep.

A personalised plan

Foods to favour and avoid, the app to track it, tips to try, and protocols sequenced to you.

Targeted supplements

Practitioner-grade supplements matched precisely to what your results reveal.

Pre / pro / postbiotics — if needed

When the findings call for it, targeted biotics to rebalance and rebuild your flora.

In plain language

Your gut hosts trillions of microorganisms, and the balance between them runs more of your overall health than most people realise. GI-MAP shows us exactly what is living in there, the helpful, the opportunistic, and the unwelcome, in measured quantities. The zonulin marker tells us whether your gut wall is doing its job as a barrier or letting through things that should stay inside.

Practicalities
Sample

Single stool collection at home, sealed kit

Preparation

Avoid antibiotics, antifungals and probiotics for two weeks before

Turnaround

Two to three weeks

After the test

Your results live in the FunctionAlps app

Findings do not sit in a PDF you never open again. They flow into your app, where your protocol, your daily tracking and your wearable data line up against what the test actually found.

  • Your protocol, built directly from the results
  • Track symptoms, food and energy against the markers that matter
  • Wearable and app data fine-tune the plan as you go
  • Re-test when it counts and watch the trend, not a single snapshot

Common questions
Yes. PCR-based detection picks up low-grade infections (parasites, H. pylori with virulence factors, opportunistic bacteria) that older culture-based stool tests routinely miss.
The evidence

Grounded in the research

Every claim on this page is anchored in published, peer-reviewed science. The studies behind it:

References ground the science of each marker — they describe the biology and published outcomes, not a guarantee of individual results.

Functional testing at FunctionAlps is used to guide nutritional optimisation within ASCA and EMR scope. It is not a medical diagnostic tool. When findings warrant medical evaluation, we coordinate with a referring physician.
