Digestive Stool Test GI Effects Gut Pathogens

Digestive Stool Test GI Effects Gut Pathogens

The GI Effects Gut Pathogen Profile is a useful profile to consider if you have had a recent gastrointestinal infection or a sudden change in bowel habits.

You might choose this profile if you are experiencing any acute digestive symptoms. It also allows you to check your progress if an initial comprehensive assessment found the presence of pathogens which you have since addressed.

The GI Effects Gut pathogen Profile is also ideal for those who have recently traveled abroad, have been camping, had exposure to untreated water, had close contact with animals or consumed undercooked meat or seafood.

Symptoms such as gas, bloating, nausea, abdominal pain, anal itching, and diarrohea may be a result of a parasitic, bacterial or fungal infection.

This smaller profile is part of the larger GI Effects Comprehensive Profile, which also provides information about the microbiome, digestion, inflammation and bacterial metabolism markers.



The methods of testing used in this test are:

PCR testing

The most up to date way of testing bacteria is to use a process called PCR, which means that the lab is looking at the DNA of bacteria. This is more sophisticated than trying to culture bacteria (grow them in a petri dish), and is important as many bacteria are anaerobic, meaning they do not live in oxygen and therefore die soon after they have left the body. This makes culturing many bacteria impossible.


The process of culturing means that the lab checks for the presence of good, bad and imbalanced bacteria and yeasts by trying to grow them in a petri dish. If they manage to grow any bacteria or yeasts such as candida, they then treat them with pharmaceutical and natural antimicrobial agents to see which are sensitive, meaning which are reduced or killed off by the agent.


Highly skilled lab technicians check for eggs and parasites and yeast with a microscope.

Please see the comparison table to see exactly which good and bad bacteria, yeasts and parasites are checked for by the GI Effects, or check out the sample report at the bottom of the page.

Your test results will also include a bacteria and mycology sensitivity panel.

In the ever-expanding world of microbial resistance, the sensitivity panel is a valuable tool to help inform which antimicrobial drugs or plant-based antimicrobials may be most effective in addressing any imbalances and /or pathogens.

Please note Plant Tannins will no longer be available as a botanical offering due to manufacturer discontinuation.


Bacterial and mycology cultures show the presence of specific beneficial and pathogenic (bad) organisms: Lactobacillus spp., Escherichia coli, Bifidobacterium. Bacterial and mycology (yeast) sensitivities are provided to guide treatment options (yeast).

Parasitology includes comprehensive testing for all parasites looking for eggs, parasites and the DNA of parasites.

  • Blastocystis spp.
  • Cryptosporidium spp.
  • Cyclospora cayetanensis
  • Dientamoeba fragilis,
  • Entamoeba histolytica
  • Giardia
  • 6 PCR targets detect common protozoan parasites including Blastocystis spp. with their subtypes which can impact on symptoms.

The full list of parasitology includes:

Nematodes – roundworms
Ancylostoma/Necator (hookworm)
Ascaris lumbricoides
Capillaria philippinensis
Enterobius vermicularis
Strongyloides stercoralis
Trichuris trichiura
Diphyllobothrium latum
Cestodes – tapeworms
Dipylidium caninum
Hymenolepis diminuta
Hymenolepis nana
Taenia spp.
Trematodes – flukes
Clonorchis/Opisthorchis spp.
Fasciola spp./ Fasciolopsis buski
Paragonimus spp.
Schistosoma spp.
Balantidium coli
Chilomastix mesnili
Cryptosporidium spp.
Cyclospora cayetanensis
Dientamoeba fragilis
Entamoeba coli
Entamoeba histolytica/dispar
Entamoeba hartmanii
Entamoeba polecki
Endolimax nana
Iodamoeba buetschlii
Cystoisospora spp.
Trichomonads (e.g. Pentatrichomonas)
White blood cells
Charcot-Leyden crystals


Clostridium difficile

Helicobacter pylori




Stool samples taken over 3 days.

Women should not collect samples while menstruating.

Do not collect if you have bleeding from haemorrhoids.

4 weeks before your test:

Wait 4 weeks from having a colonoscopy or barium enema before starting the test.

2 weeks before your test:

Wait until you have finished any course of antibiotics, antiparasitics, antifungals, probiotic supplements (acidophilus, etc.) or consuming food products containing beneficial flora (e.g. Activia®).

2 days before your test:

Refrain from taking digestive enzymes, antacids, and aspirin for two days prior to specimen collection, unless otherwise instructed by your GP or practitioner.

Lactoferrin supplements: whilst these will not have a direct impact on the test results, they can have an indirect influence owing to the support they provide to the gut wall. Lactoferrin is good for permeability and the overall health of the gut wall. You may like to consider waiting for 72 hours after taking lactoferrin supplements before completing your test samples.

There are no age limits for this test but the reference ranges set by the lab are for children over the age of 5.  This test can still be valuable when looking at microbial balance and when looking for pathogens.

Please return via a next day service Monday – Thursday only. The samples must be stored in the fridge prior to returning.

A courier option is sent with your test kit. You pay the laboratory directly for this test and also the return courier if you use the service. You can also make your own arrangements for returning your samples via a next day service.


17-19 working days.

Your test results will be emailed to you.
