Comprehensive Digestive Stool Test GI effects

What does this test cover and who is it suited for?

The GI Effects Comprehensive Stool Profile is very useful for patients who are looking to find out the root cause of their digestive symptoms including bloating,abdominal pain, diarrhea, gas, and constipation.

What markers does this test cover?

Pancreatic Elastase-1 is a marker of exocrine pancreatic function.
Products of Protein Breakdown are markers of undigested protein reaching the colon.
Fecal Fat is a marker of fat breakdown and absorption.
All of the above will help you understand if you are breaking down and absorbing your foods correctly.
Calprotectin this marker is very useful in differentiating Inflammatory Bowel Disease (IBD) from rritable Bowel Syndrome (IBS).
Eosinophil Protein X is a marker of eosinophil-driven inflammation and allergic response.
Fecal Secretory IgA is a marker of gut secretory immunity and barrier function.
Gut Microbiome:
Metabolic indicators, including short-chain fatty acids and beta-glucuronidase, demonstrate specific and vital metabolic functions performed by the microbiota.
Commensal Bacteria demonstrate the composition and relative abundance of gut organisms
Bacterial and mycology cultures demonstrate the presence of specific beneficial and pathological organisms.
Bacteria and mycology sensitivities – This marker will look at dybiotic bacteria and yeast species including Candida Albicans


GI Effects provides microscopic fecal specimen examination for ova and parasites (O&P), the gold standard of diagnosis for many parasites.

Enzyme immunoassay (EIA), widely recognized for its diagnostic utility in the detection of pathogenic antigens, is used for the identification of Cryptosporidium, Entamoeba histolytica, and Giardia lamblia.

Additional Biomarkers Available:

  • Campylobacter
  • Clostridium difficile
  • Escherichia coli
  • Fecal Lactoferrin
  • Helicobacter pylori
  • Macro Exam for Worms
  • Stool Zonulin
  • KOH Preparation for Yeast

What Will I be able to do with the results?

If a patient is suffering from diarrhea, the results may indicate that he or she may have parasites, yeast, bacteria or inflammation.

All of these markers are useful for consultants to assess the best treatment.

GI Effects® uses anaerobic bacteria PCR molecular assay, Matrix Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) technology for cultivable species identification, as well as stool-based biomarkers for gastrointestinal diagnostics.

How much does it cost? £355.00

Comprehensive Stool Analysis- CSAP

This test covers the following markers:

The Comprehensive Parasitology profile is a non-invasive stool test that evaluates the presence of parasites, beneficial bacteria, imbalanced gut flora, pathogenic bacteria, and yeast. This sensitive stool test is ideal for patients with sudden changes in bowel pattern, especially for those who have recently traveled, been camping, or may have had exposure to untreated water. The Comprehensive Parasitology Profile test can help reveal hidden causes behind acute or chronic conditions that may develop from parasitic infection or an impaired or imbalanced gut microbiome.

The Comprehensive Parasitology Profile allows clinicians to identify parasitic infections, as well as microbial imbalances, and to target treatment protocols that can help rebalance the gut and resolve infection.

Friendly gut Bacteria – Lactobacillus, Bifidobacteria, Enterococcus species
Bacteria and mycology sensitivities – This marker will look at dybiotic bacteria and yeast species including Candida Albicans


GI Effects provides microscopic fecal specimen examination for ova and parasites (O&P), the gold standard of diagnosis for many parasites.

Enzyme immunoassay (EIA), widely recognized for its diagnostic utility in the detection of pathogenic antigens, is used for the identification of Cryptosporidium, Entamoeba histolytica, and Giardia lamblia.

How much does it cost? £290

Our CSA test is also able to analyse at least 30 markers including:


  • Inflammation/Immunology
  • Gut Micriobiome including beta glucoronidase
  • Friendly Bacteria such as Lactobacillus or Bifidobacteria
  • Bacterial and mycological culture, which demonstrate the presence of specific beneficial and pathological organisms-Klebsiella and Citrobacter freundii and Enterobacter Clocae.

Candida-We can also detect Candida albicans and Geotrichum species via stool analysis. The stool test is also able to determine the most appropriate anti-fungals to eradicate candida.


Parasites tested for include: Cryptosporidium, Entamoeba histolytica, and Giardia lamblia, Blastocystis hominis and Dientamoeba fragilis and Giardia
Most patients who have been to the NHS with symtoms of IBS, are often offered, Mebeverine or Colofac or Omeprazole and unfortuantely for many patients these drugs do not really help their symptoms. As functional medicine practitioners, we look at the possible causes of your symptoms so we can try and alleviate the uncomfortable symptoms of IBS and improve your quality of life. This is why a stool test can be extremely helpful in detecting imbalances in gut health.

Gut Microbiome

Research indicates that our intestinal tract, contains millions of organisms, also know as the gut microbiome . If imbalances exist in the gut mcrobiome there may be links with a number of conditions including Inflammatory Bowel Disease, Irritable Bowel syndrome (IBS) and Autism, Obesity and autoimmune conditions.

This test has been a huge breakthrough in helping us identify imbalances in gut health such as IBS.

GI-MAP Microbial Assay Plus


The GI-MAP 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.

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. With full quantification, we can now see the level of infectionthus, the GI-MAP arms the clinician with accurate, actionable clinical information.

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

Other key tests that are may be very beneficial for IBS include, SIBO, Candida and food intolerance tests

For some clients, sometimes only one of the above is to blame. However, for many of my clients , 2 or more of these triggers may be present simultaneously. For example, there may be a presence of yeast such as candida as well as food intolerances. In that case we will need to look at anti-funglas as we as diet. The beauty of the stool test is that it will tell you exactly what anti-funglas you need to take to eradicate the yeast in question.

Many people only look at one possible cause of IBS. The comprehensive stool test looks at, yeast, bacteria and parasites and is extremely reliable.

The Comprehensive Stool test will find triggers that are not even looked for by standard tests done on the NHS. In fact the NHS does not even believe in Candida or Yeast!

We also use food intolerance tests. These tests can be very helpful in helping symptoms and we work with each patient to ascertain exactly what diet is needed – in their particular case. Most clients benefit very quickly from any improvements in health.
