GI-MAP plus Zonulin


The GI MAP has now been replaced by the newer

GI EcologiX gastrointestinal health and microbiome profile



If you have any uncomfortable digestive conditions the GI-MAP gut health test is arguably the best available and offers valuable insight into the health of your digestive system. It uses cutting edge DNA technology to provide incredible insight into numerous digestive and immune markers.

The GI-MAP Microbial Assay Plus

The GI-MAP was designed to assess a patient’s microbiome from a single stool sample, with particular attention to microbes that cause disease or that disrupt normal microbial balance and contribute to perturbations in the GI flora and contribute to illness. It’s much more convenient than a 3 day sample so it’s easier to do and the results provide you and your nutritional therapy practitioner with lots of useful information to provide the structure and direction of your personalised nutritional therapy protocol. The GI-MAP arms the informed nutritionist with accurate, actionable clinical information.

This is the first and only gut test in the world to be running full quantitative PCR (qPCR) on multiple GI targets, including pathogens, bacteria, worms, yeasts, parasites and comprehensive antibiotic resistant genes, alongside intestinal health and immune markers.

Tests need to be booked in conjunction with a suitable nutrition consultation to help you understand what the test results mean for you and what you can do to support your gut health.

This GI-MAP DNA stool analysis test provides information on the following markers of digestive or gastrointestinal health or imbalance;

  • Pathogenic bacteria, toxins, parasites and viruses
  • Commensal bacteria (inc. B.fragilis)
  • Bacterial autoimmune triggers
  • Dysbiotic bacteria
  • Phyla microbiota ratios
  • Opportunistic parasites
  • Worms
  • Yeast, fungi and moulds
  • Secretory IgA (sIgA)
  • Anti-gliadin sIgA
  • Pancreatic elastase 1
  • Steaotocrit
  • Beta-glucuronidase
  • Calprotectin
  • Faecal Occult blood
  • Antibiotic resistance genes
  • Zonulin (faecal)

For more information on the methodology and markers, please see the white paper, which has over 190 peer reviewed references.
