Organisms in the digestive tract, such as bacteria, parasites and viruses can be the underlying cause of many digestive conditions and illnesses.
About this test
The GI-MAP is the first and only gut test in the world to be running full quantitative qPCR, meaning DNA testing on multiple Gastro intestinal targets, including pathogens, bacteria, worms, yeasts, parasites and comprehensive antibiotic resistant genes, alongside intestinal health and immune markers.
The GI-MAP was designed to assess a patient’s microbiome ( gut bacteria ) from a single stool sample, with particular attention to microbes that cause disease or that disrupt normal microbial balance and contribute to changes in the GI flora and contribute to illness. With full quantification, we can now see the level of infection thus, the GI-MAP arms us with accurate, actionable information.
What is being measured
A summary of what is being tested:
- Pathogenic bacteria, toxins, parasites and viruses
- Commensal / Normal bacteria including Bacteroides fragilis group, Bifodobacter, Enterococcus, bifido & Lactobacillus
- Dysbiotic Bacteria – including Morganella morganii, Pseudomonas species & Streptococcos species
- Bacterial Autoimmune Triggers – including Proteus mirabilus, Proteus spp & Klebsiella pneumoniae
- Opportunistic Parasites – including Blastocystic Hominis, Dientamoeba Fragilis & Endolimax nana
- Yeasts, fungi and moulds; including the Candida species, Cyclospora, Geotricum species & Trichosporon species
- Helicobacter pylori and virulence factors
- Phyla microbiota ratios
- GI Health Markers including;
Secretory IgA (sIgA)
Pancreatic elastase 1
Faecal Occult blood
For the full list of what is being measured, see the sample report at the bottom of the page.
A little about a few of the markers in the test.
Blastocystis hominis – also tested using PCR – which checks for the DNA of the parasite.
Blastocystia hominis is a parasite commonly found in the GI tract. Symptoms of infection include:
- Abdominal cramps
- Weight loss
Candida species are constituents of a normal healthy gut flora however if an overgrowth of the yeast (candidosis) occurs, gut permeability can increase leading to leaky gut syndrome. This can allow the yeast hyphae to penetrate the gut wall lining resulting in potential systemic infections.
Helicobacter pylori is commonly thought to be the bacteria responsible for causing stomach ulcers, gastritis and virtually all abdominal ulcers, apart from drug-induced forms. It survives the acidic environment of the stomach and infection can lead to pain and inflammation, which over time can significantly increase the risk of gastric cancer. There is also the h. pylori breath test available by following the link.
You can opt to add on zonulin family peptide to this test if you prefer. Zonulin is gut a marker associated with intestinal permeability / Leaky gut.
Age range this test is suitable for
Suitable for all ages. Children need to be potty trained and out of nappies. The sample must not be contaminated with urine or fibres from nappies.
The GI-MAP can be run on a patient of any age, from infants to adulthood. The main thing to bear in mind when testing for a child under the age of 2 is that the results will more indicative of any issues, rather than an accurate reading of the overall health of the microbiome. This is because in children under 2, the microbiome has not fully developed yet and so this would need to be considered during the analysis of the report
1 single stool sample
Before taking the test
You will need a break after you have finished any anti-microbial programmes before being able to complete this test otherwise you risk having false negative results. The length of the break depends on the medication. We often recommend 2 weeks after antibiotics or antimicrobials.
Samples must arrive back at the lab within 3 days of collection and must be shipped on a Monday, Tuesday or Wednesday. Please check there isn’t a bank holiday if the Monday falls on day 3.
European customers will receive their test kits via courier delivery. A return courier collection of the samples is included in the shipping fee of £30.
Non European customers please email email@example.com to make an enquiry.
7-9 working days
