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:

  • Proteus sp.
  • Klebsiella sp.
  • Enterobacter sp.
  • Citrobacter sp.
  • Pseudomonas sp.
  • Other aerobic bacteria
  • Bifidobacterium sp.
  • Bacteroides sp.
  • Lactobacillus sp.
  • Clostridium sp.
  • Candida albicans
  • Candida sp.
  • Geotrichum sp.
  • Mold

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 intestinal bacteria, candida albicans, candida spec., geotrichum spec. and mold 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. Moreover, additional information can be found on our website, particularly within various test categories, “health conditions,” and the Frequently Asked Questions (FAQs) section. If you have any further inquiries, please feel free to reach out to us by sending an email to

Test measures
For the Gut Flora & Biome Test we analyse:
  • Proteus
  • Klebsiella
  • Enterobacter
  • Citrobacter
  • Pseudomonas
  • Other aerobic bacteria
  • Bifidobacteria
  • Bacteroides
  • Lactobacilli
  • Clostridia
  • Candida albicans
  • Candida spec.
  • Geotrichum spec.
  • Mold
Proteus spec.

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.

Klebsiella spec.

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.

Enterobacter spec.

Increased Enterobacter 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.

Citrobacter spec.

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.


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.

Bifidobacterium spec.

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.

Bacteroides spec.

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).

Lactobacillum spec.

Lactobacilli are lactic acid forming bacteria, which produce large amounts of short chain fatty acids (SCFA). SCFAs lower the intestinal pH and thereby make the gut milieu acidic — unsuitable for microbial pathogens (e.g. yeasts). In addition, lactobacilli secrete antifungal and antimicrobial agents. Decreased Lactobacilli indicate disturbances of the intestinal flora.

Clostridium spec.

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.

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 spec.

Geotrichum 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 mold 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 mold or help you get rid of it. Antibiotics are also a common cause of mold 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
  • Dermatosis
  • Sleeping disorders

    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:

What exactly is the Gut Flora & Biome Analysis?

Gut Flora & Biome Analysis is an extensive examination of your intestine based on your stool sample. It provides insights into the composition and balance of microorganisms in your digestive tract.

Why is the intestinal 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 gut flora impact our health?

A disturbed gut flora can lead to various health issues including allergies, autoimmune diseases, frequent infections, rheumatism, cancer, and even weight gain. Factors like antibiotics therapy can disrupt the balance of gut flora significantly.

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.
