This Great new health test offers the best way for checking levels of bacteria. Not only does it check by culturing bacteria (Growing it) but it also uses a new technology PCR which looks at the DNA of the bacteria in the stool and is fast becoming the world leader in ways to test for bacteria.
What is being measured
Microbiology Markers – Microbiome
This part of the test is looking at levels of good and bad bacteria, yeasts and parasites.
PCR technology is used to test for the presence of the DNA of bacteria – the new and more comprehensive way that levels of different bacteria are checked. The different types of bacteria checked are;
Bacteriodes- Prevotella group
Firmicutes/Bacteriodes (F/B Ratio)
Bacteriology – Cultured
Additional Bacteria – Cultured
A board range are tested for and can include;
Citrobacter frendii (and other strains of citrobacter)
Klebsiella (many strains)
The presence of some bacteria may be clinically relevant in those with bacterial gastroenteritis, including: traveler’s diarrhoea, food poisoning, IBD and/or IBS.
Mycology – Cultured
Candida dubliniensis and other species of candida are checked for.
Yeast that are not related to candida.
Opportunistic fungi are associated with gastrointestinal symptoms and may be considered pathogenic, especially in immune-compromised individual
A Sensitivity panels is provided against any of the additional bacteria or yeasts that may be pathogenic (problem causing) which will show which pharmaceutical medicines and plant based supplements will be effective and which they are resistant to and would there for would be ineffective.
The GI Effects profile utilizes the accepted gold standard for parasite detection, the microscopic Ova & Parasites (O & P) exam. O & P approaches have the highest proven diagnostic and clinical utility for parasite detection. While governing bodies, such as the Centers for Disease Control, recommend a minimum of three samples on at least three separate days for the highest parasite detection, literature suggests that > 90% of enteric parasitic infections are detected in a single stool sample using O & P collection. In addition, Cryptosporidium, Giardia lamblia, and Entamoeba histolytica/dispar are assessed by EIA Enzyme immunoassay.
Additional Markers – The following markers below can be added on for an additional fee. Please add these at check out should you like to include them in your test.
Stool Zonulin Family Peptide – Research by Fassano concluded that zonulin acted like a shoe lace to pull the cells of the intestines together. If it was found outside of the reference range it was concluded that it was associated with a leaky gut or intestinal permeability. A recent research paper published in Frontiers in Endocrinology suggested that the zonulin kits from Immundiagnostik (IDK) ( who supply All the labs that we know that run zonulin) did not detect zonulin (a precursor of Haptoglobin 2). This issue was further confirmed by the kit manufacturer, Immundiagnostik. Because some researchers are conducting studies and have received data from the current zonulin kits, Genova are still offering zonulin but have renamed it Zonulin family peptide.
The Scheffler paper suggests that the kits may detect properdin, a protein involved in the alternative complement pathway and inflammation. Preliminary study results from an external investigator suggest that properdin may be structurally and functionally similar to zonulin. When analysing data Genova found a high correlation with raised zonulin and other markers associated with gut mucosal health.
Helicobacter Pylori – EIA. Recent studies have shown that up to 45 – 50% of the world’s population may harbor H. pylori. Many carriers are asymptomatic, but H. pylori is known to have a causative role in ulcers, chronic gastritis, and stomach cancer. Direct stool testing of the antigen (HpSA) is highly accurate and is appropriate for diagnosis and follow-up of infection.
Campylobacter spp – EIA. Campylobacter jejuni is the most frequent cause of bacterial-induced diarrhea. While transmission can occur via the fecal-oral route, infection is primarily associated with the ingestion of contaminated and poorly cooked foods of animal origin, notably, red meat and milk. Symptoms range from mild to severe abdominal pain, diarrhea, fever, malaise; lasting several days to several weeks.
Clostridium difficile EIA. Clostridium Difficile also known as C.Diff is an anaerobic, spore-forming gram-positive bacterium. Changes in gut flora, usually caused by antibiotics can lead to colonization with Clostridium difficile. Symptoms include inflammation, abdominal pain, cramping, fever, and diarrhea. Symptoms often present during antibiotic use and often subside once antibiotics are discontinued.
E. coli EIA is a group of bacterial strains that have been identified as worldwide causes of serious human gastrointestinal disease. Enterohemorrhagic E. coli includes over 100 different serotypes; 0157:H7 is the most significant, occurring in over 80% of all cases. Contaminated food continues to be the principal vehicle for transmission; foods associated with outbreaks include alfalfa sprouts, fresh produce, beef, and unpasteurized juices. The symptoms may include severe abdominal cramps and diarrhea and bloody diarrhea.
KOH Prep. A KOH prep is a further way to test for yeast
Fecal Lactoferrin –In the gastrointestinal tract, lactoferrin serves as a non-specific marker of inflammation
Microscopic exam for worms. Examination for adult cestodes, nematodes and trematodes or macroscopic worms or pieces of worms that may be shed in the stool.
Sample requirements – stool
You will need to send your sample back to the lab via a next day postal service – If you are in the UK, Royal mail offer a suitable next day service. If you are outside of the UK then please check with your postal service for options. The cost of the test does not cover the return postage.
Please note that samples should only be posted on Monday – Thursday so that they do not arrive over the weekend when the lab is closed.
A courier returns option is offered by the lab and details will be included in with your test kit. This is an optional service and the cost is not included in with the test fee. Details about payment, should you wish to take up this offer, are included with the courier details.
Age range this test is suitable for
Adults and children 2 years and above. The child needs to be potty trained and out of nappies. The sample must not be contaminated with urine or fibres from nappies.
Before Taking this Test
Refrain from taking digestive enzymes, antacids, and aspirin for two days prior to specimen collection, unless otherwise instructed by your healthcare provider
If taking antibiotics, antiparasitics, antifungals, probiotic supplements (acidophilus, etc.), or consuming food products containing beneficial flora (e.g. Activia®), it is recommended that you wait a minimum of 14 days after your last dose before beginning the test; 28 days may be preferred after antibiotics have been utilized (unless instructed otherwise by your physician). There may be times when your healthcare provider prefers that you stay on one of these agents (e.g. acidophilus) during testing in order to evaluate its effectiveness. Follow your healthcare provider’s recommendation.
Never discontinue prescription medications without consulting your healthcare provider first.
The test kit will come with full instructions.
