Who should take the test?

Are you suffering from chronic diseases? Concerned about your increased susceptibility for infections? Perhaps you have just completed an antibiotics therapy?

Gut flora is the complex community of microorganisms that live in the digestive tracts of humans and animals. The healthier and more balanced our gut flora is, the healthier we are. A disturbed gut flora, however, can be the cause of many diseases – whether allergies, autoimmune diseases, frequent infections, rheumatism or cancer. Even overweight is sometimes associated with a disturbance of the gut flora. Above all, frequent intake of antibiotics damage the gut flora sustainably. A comprehensive health prevention therefore always includes the development of a healthy gut flora.

The test analyzes the values of the following analytes:

  • Escherichia coli
  • Proteus
  • Citrobacter
  • Klebsiella
  • Other enterobacteriaceae
  • Enterococci
  • Pseudomonas
  • Bacteroides
  • Bifidobacteria
  • Lactobacilli
  • Clostridia
  • pH-Value
  • Candida albicans
  • Candida spec.
  • Geotrichum candidum
  • Yeast

Our Gut Flora & Biome Analysis may be interesting for people who have just completed an antibiotics therapy, people suffering from chronic diseases or an increased susceptibility for infections and all those who just want to actively do something for the preservation of their health.

How does it work?

You collect the samples at home, send them back to us and we will provide you with your level of each analyte and whether your level falls within the reference ranges for your age. In addition to that, the results include graphs showing whether your levels are in the “green” (=normal/healthy) or “red” (=too high/low) area, making it easy to understand the results.

What will my results tell me?

Your results will provide detailed information about whether your escherichia coli, proteus, citrobacter, klebsiella, other enterobacteriaceae, enterococci, pseudomonas, bacteroides, bifidobacteria, lactobacilli, clostridia, pH-Value, candida albicans, candida spec., geotrichum candidum and yeast levels are normal, low, or high compared to reference ranges in your age group. You can then discuss the results with your doctor or health practitioner, who can give you further guidance and treatment recommendations.

What guidance will I get along with my results?

We always recommend the discussion of the mailed results with your doctor or practitioner. Besides, further information is available on our website, especially in the different test categories, under “health conditions” and the FAQs. Still have questions? Then you can contact us by mail at

Escherichia coli

Escherichia coli (E. coli) is a minority member of the gut microbiome, but a very important one. E. coli bacteria normally live in the intestines of healthy people and stimulates the intestinal immune system. It aids digestion and protects us from other harmful microbes. E. coli ferments to produce folic acid, vitamin K2 (this protects against osteoporosis) and Co-enzyme Q10 (essential for mitochondrial function). If there are low counts of E-coli, one can expect problems like osteoporosis and bone problems, mitochondrial function, low mood and poor gut motility. Increased E. coli indicates putrefaction in the intestine and may burden the body with metabolic toxins. Potential causes may be reduced immunity of the intestinal mucosa, low counts of bifidobacteria or excess supply of protein.


Proteus species are most commonly found as part of normal human intestinal flora, along with Escherichia coli and Klebsiella species. Proteus is also found in multiple environmental habitats, including long-term care facilities and hospitals. As a particularly active proteolytic germ, proteus can burden the body considerably through its metabolic toxins.


Citrobacter is a rod belonging to the Enterobacteriaceae family. It is considered an opportunistic pathogen and therefore can be found in the gut as part of the normal flora. Citrobacter are also commonly found in water, soil and food and may be spread by person-to person contact.


Klebsiella is a bacterium, which belongs to the Enterobacteriaceae family. Klebsiella can be found in the gastrointestinal tract of humans. Klebsiella overgrowth is commonly asymtomatic. Some strains of Klebsiella may cause diarrhea and some are enterotoxigenic. A low-starch diet may be helpful if high levels of Klebsiella are present.

Other enterobacteriaceae

Increased enterobacteriaceae indicate disturbances of the intestinal flora, malnutrition or digestive insufficiencies. A larger amount of these bacteria does not belong in the normal intestinal flora. Their multiplication often results from past antibioses.


Decreased Enterococci in the stool indicates disturbances in balance of the intestinal flora. Enterococci produce short-chain fatty acids during the carbohydrate utilisation, which contributes to the acidification and stabilisation of the intestinal environment. As an important contribution to the intestinal milieu, they produce bacteriostatic substances.


Pseudomonas can be found in water and soil as well as fruits ans vegetables. A common source of infection is bottled water, but increased Pseudonomas may also be due to an earlier antibiotic therapy.


Bacteroides is the most abundant bacteria in the microflora, which allows us to digest soluble fibre and make short chain fatty acids. Decreased bacteroides indicate a lowered resistence to pathogenic species (such as salmonella, shigella and clostridia).


Bifidobacteria make up a significant portion of the human gut flora. Along with Lactobacillia and Enterococci, Bifidobacteria control potentially pathogenic organisms and stimulate the intestinal immune system (GALT). Bifidobacteria metabolize carbohydrates only. By doing so, they produce short chain fatty acids, which adidify the intestine and couteract pathogenic organisms. Decreased Bifidobacteria indicate deficiencies in colonisation resistance, putrefaction in the intestine and can promote constipation.


Lactobacilli is a lactic acid forming bacteria, which produces large amounts of short chain fatty acids (SCFA). SCFAs lower the intestinal pH and thereby make the evironment alkaline and unsuitable for microbial pathogens (e.g. yeast). In addition, Lactobacilli secrete antifungal and antimicrobial agents. Decreased Lactobacilli indicate disturbances of the intestinal flora.


Clostridia are prevalent flora in a healthy intestine. As clostirida produce gases it may cause flatulence. Increased Clostridia indicates putrefaction in the intestine and may burden the body with metabolic toxins. Increased clostridia are often found in older people due to changes in their nutrition. Clostridium difficile and Clostridium perfringens are one cause of antibiotic-associated diarrhea.


Fecal pH is influenced by numerous factors, but is largely dependet on the fermentation of fiber by the beneficial flora of the gut. With a balanced diet the fecal pH should lie between 6,2 and 6,8. Acid fecal pH indicates disorders of intestinal ecology. An alkaline fecal pH indicated an imbalanced intestine flora. It is possible that proteolytic putrefactive germs are predominant, which raise the fecal pH through alkaline metabolites (e.g. due to a high-protein diet).

Candida albicans

The genus Candida is comprised of approximately 200 different species. Candida albicans is the most common strain of them. It is a normal part of the gut flora and most people have some level of Candida albicans in their intestines. But a combination of factors can lead to an overgrowth, which then leads to several undesirable symptoms including fatigue, weight gain, joint pain, and gas.

Candida spec.

Increased candida species indicates deficiancies in colonisation resitance, disturbances of the intestinal flora and or a defect mucosa. Candida species may burden the body with toxic metabolites. Some patients respont to even low rates of yeast overgrowth.

Geotrichum candidum

Geotrichum candidum belongs to the Endomyceteaceae family. This organism can be found in soil, dairy products and in human skin and mucosae. Symptoms of Geotrichum infection have been associated with diarrhea and enteritis.


An infection with yeasts can have many reasons. Possible causes are things like corticosteroid therapy, stress, diabetes, malnutrition or birth control pills. All of them weaken the immune system and a weakened immune system cannot control yeast or help you get rid of it. Antibiotics are also a common cause of yeast infection because they destroy the good bacteria that keep it under control.

Symptoms the Gut Flora & Biome Test is suitable for:
  • Chronic diseases
  • Increased susceptibility for infection
  • Flatulence
  • Diarrhea
  • Nausea
  • Fungal diseases
  • Stomach pain
  • Overweight
  • Vitamine deficiency
  • Migraine

    I have been getting more and more unhappy with my physicians’ treatments, as I felt like he didn’t take me or my problems seriously. It felt really good to take my healthcare back into my own hands with this test. It basically confirmed my thoughts that something was wrong with my gut flora. Needless to say, I went to another physician for treatment and with these test results I could prove what was wrong.

Any Questions?

Here are some of the most frequently asked questions regarding this test. Your question is missing? Please contact us at:

Why is the instestinal flora so important?

The intestinal flora is an important part of our immune system. The bacteria it contains not only break down our food, they also keep intruders away or prevent them from spreading. A damaged intestinal flora is the cause of numerous health problems.

How does antibiotic therapy affect gut flora?

Antibiotics can disrupt the balance of gut flora by killing both harmful and beneficial bacteria. This disruption can lead to digestive issues, susceptibility to infections, and other health complications.

What does the Gut Flora & Biome Analysis measure?

The analysis assesses the levels of various analytes including Escherichia coli, Proteus, Citrobacter, Klebsiella, Enterococci, Pseudomonas, Bacteroides, Bifidobacteria, Lactobacilli, Clostridia, pH-Value, Candida albicans, Candida spec., Geotrichum candidum, and Yeast.

For whom is a Gut Flora and Biome Analysis useful?

The analysis is particularly useful if there is a suspicion that the intestinal flora could be damaged. This can happen especially after taking antibiotics, since not only the "harmful" but also the "good" bacteria are being destroyed. A few months after antibiotic therapy, it should therefore be checked whether the intestine has regenerated or whether an gut renovation using probiotics would be a good idea.

Why is an additional test for Candida and intestinal fungi included in the analysis?

Candida infections are often associated with a damaged intestinal flora. A damages intestinal flora is no longer able to stop the multiplication of fungi, which otherwise only occur to a small extent. There follows a rapid spread, whereby the fungi further damage the intestine due to the toxins they secrete. In order to be able to react with adequate therapy, it is therefore advisable to check both bacteria and fungi.
