GI-MAP plus Zonulin

A precise read of your gut microbiome and barrier integrity

  • 80+ microbial targets, quantified by DNA-level PCR
  • Beyond pathogens: gut barrier (zonulin), inflammation, immunity & digestion
  • Detects parasites, H. pylori and fungal overgrowth others miss
  • Simple at-home stool collection, no clinic visit
  • Read in functional ranges and built into your personal protocol

How this test can help

Select the area and specific problem to see exactly how we approach it through this test.

Digestive health

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

From data to action

Precise markers mean precise actions. Once the test shows what is actually driving the pattern, the plan can target that, instead of guessing.

ClearGas-forming overgrowthA specific protocol for the species driving fermentation.
SupportDigestive capacitySpecific supplements where breakdown is falling short.
RebuildMotility and floraFeed the strains that keep transit moving.
RefineFermentable foodsSet how tightly to pace FODMAPs, and for how long.

Where we focus

GI-MAP is not a single number, it reads four connected layers of gut health at once.

1 stool sample · 80+ microbial targets
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.

Read together, these four layers show which organisms are driving the pattern, whether the barrier is holding, and how well you are breaking food down.

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
Often paired with

Most people run one test. Where a second genuinely adds an answer the first cannot give, this is the pair we reach for.

The people behind your results

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

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.

Nordic Laboratories

Nordic Laboratories

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.

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

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.
