includes Zonulin

The GI-MAP test with Zonulin (Microbial Assay Plus) utilizes advanced techniques including qPCR quantitative polymerase chain reaction for accurate detection of parasites, yeast, bacteria, helicobacter and viruses and inflammation. The test will also analyse the DNA of all organisms.


The test comes as standard with Zonulin,  a marker for leaky gut.   Zonulin
increases intestinal permeability in the jejunum and ileum and is considered a
biomarker for barrier permeability.


The test is carried out by Diagnostic Solutions.

The GI MAP test may help with the following conditions:

  • IBS
  • Inflammatory Bowel Disease
  • Digestive complaints, diarrhea or constipation
  • Brain fog/fatigue
  • Skin problems, like acne and psoriasis
  • Depression and anxiety
  • Diabetes and weight loss issues
  • Autoimmune conditions

What type of pathogens does the test look for?

Please see a GI MAP sample report here:

The GI-MAP includes pathogens (bacterial, parasitic, and viral) commonly known
to cause intestinal gastroenteritis. These include:


Clostridium difficile,
Toxin A and Toxin B

Enterohemorrhagic E. coli

Enteroinvasive E. coli / Shigella

Enterotoxigenic E. coli LT/ST

Shiga-like Toxin E. coli stx1


Vibrio cholera

Yersinia enterocolitic


What parsites does it test for?


Entamoeba histolytica


Blastocystis hominis

Chilomastix mesnii

Cyclospora spp.
(Cyclospora cayetanensis)

Endolimax nana

Entameoba coli

Pentatrichomonas hominis
Ascaris lumbricoides (Roundworm)

Ancylostoma duodenale and
Necatur americanus (Hookworms)

Taenia spp. (Tapeworm)

Trichuris trichiura (Whipworm)


Who should use the GI-MAP test?
If you have symptoms of IBS and would like to test for leaky gut and inflammation as well as parasites, yeast and bacteria this test is a good choice. If your GP has already ruled out IBD, a gut pathogens test may be another option.

What GUT health markers does the GI-MAP test for?

Symptoms may include:

  • Pancreatic Elastase 1
    Elastase 1 is a digestive enzyme secreted
    exclusively by the pancreas, giving a
    direct indication of pancreatic function.
  • Occult Blood Fecal
    Immunochemical Testing (FIT)
  • Steatocrit
    Fecal fats are normally emulsified by bile
    salts and absorbed in the small intestines.
    High levels of fat in the stool may be an
    indication of maldigestion, malabs
  • Beta-Glucuronidase
    High levels of fecal beta-glucuronidase can
    indicate unfavorable metabolic changes in
    the colon.

What ELSE does the test measure?


is the gold standard marker for the
diagnosis and monitoring of inflammatory
bowel disease. It is used to differentiate IBD
from irritable bowel syndrome

Beneficial bacteria  including Bacteroides fragilis, Bifidobacterium spp Lactobacillus spp. Akkermansia municiphila, Faecalibacterium prausnitzi and Enterococcus spp and Roseburia spp.

Bad bacteria  such as Klesbiella and Enterobacter Clocae, Streptococcus

Yeast/ Fungal Organisms  such as Candida Albicans, Geotrichum, Microsporidium and Rhodotorula. If these organisms overgrow they may cause illness in certain individuals.



How does the test work?
Patients need to send in only one  sample to the laboratory.

This is an excellen stool test to assess at bacteria, yeasts, viruses and parasites all via the new PCR  ad DNA testing. This test also offers some digestive health markers to assess your ability to digest and absorb food.

Please fill in the contact form below, or  e-mail us at  or call us on 0345 129 7996 if you wish to order this test and we will send you a payment link.



    Specifically the GI Map  Comprehensive Stool Analysis (CSA)  measures the following markers:

    •  Zonulin- please note many labs do not incude this as standard
    • The status of Beneficial bacteria, including Lactobacillus spp. and Bifidobacterium spp.
    • Viruses
    • Helicobacter Pylori
    • Dysbiotic or foreign bacteria including Klesbiella
    • Salmonella, E-coli, Sigella
    • The presence of any Parasites, including Giardia lamblia and Cryptosporidium
    • Yeast/fungal overgrowth, commonly referred to as Candida albican
    • Digestion of food, which indicates absorption status of nutrients
    • IBD markers identifying underlying inflammation associated with Inflammatory Bowel Disease including Calprotectin
    • Secretory IgA. Deficiency of SIgA is the most common immuno-deficiency marker
    • Occult blood
