Gut Flora Test

Intestinal Microbiome

Your gut flora is as unique as your fingerprint - but it says much more about your health. Scientists are currently investigating the numerous connections of the microbiome and health. For example, there is much evidence that bacteria in the gut flora influence how quickly you gain and lose weight. The diversity of your gut flora is probably related to gut health and the risk of illnesses. The right intestinal bacteria protect the body from diseases and digestive problems.

Information About the Gut Flora Test

Why Test The Gut Flora?

The gut flora is a mirror of your health condition. Intestinal bacteria are important for your digestion and immune system and are influenced by your lifestyle. An unhealthy or imbalanced diet, harmful substances, smoking, antibiotics and stress can throw the microbiome out of balance. Scientific studies indicate that this has an effect on the digestion and can even increase the body weight.

A DNA analysis of the gut flora is usually not carried out by a medical practitioner. With the cerascreen® Gut Flora Test, you do not have to go to a clinic and do not have to wait for appointments. You will receive detailed, illustrated instructions and can take the sample quickly, conveniently and discretly from home.ß. You will then receive your individual gut flora profile.

Conventional intestinal flora tests analyse the stool sample by placing it on a Petri dish and looking at it through a microscope. However, this method only shows a section of the gut flora. More accurate, modern and highly diagnostic is the rRNA sequencing that is being applied for the cerascreen® Gut Flora Test: This involves analysing the DNA of all bacteria in the stool sample.

Frequent Questions about the Gut Flora

  • Why take the Gut Flora Test?

    Do you wonder why you gain weight faster than others? What does the diet do to the bowels? Where do tummy rumbles and digestive problems come from? Why do I have a constant cold? Is my bowel healthy - and how do I actually find out? In this case, the Gut Flora Test is just right for you. Because the bacteria in your gut reveals answers to these and other questions.

    Studies indicate that our gut flora controls how fast we gain weight, how well we digest carbohydrates, fat and other nutrients, how effectively our immune system fights off pathogens and much more.

    The intestinal bacteria even transmit signals to the brain and may be related to your mood and the emergence of depression. If you learn more about your intestinal flora, you will gain insights into your physical and mental health as well.

    All these and other topics are currently the subject of exciting scientific research, which we keep you up to date on in our Health Portal and our newsletters.

    We still talk far too rarely about digestive problems and the gut. Unfortunately, these are still often unaddressed taboo topics. The cerascreen® Gut Flora Test gives you insights into your intestinal health and you can carry out the test discretely at home - simple, fast and safe.

  • Who should take the Gut Flora Test?

    The Gut Flora Test is worthwhile for every adult (as of 18 years) who wants to learn more about the complexity in their gut.

    The Gut Flora Test is also interesting for people who have to take antibiotics frequently. Because antibiotics do not just kill disease-causing bacteria, they can also affect the "good" gut bacteria negatively and reduce their diversity. After an antibiotic therapy, it can take up to six months for the gut flora to recover.

    Other factors that affect your gut flora include your genetic predisposition, medication, smoking, stress and environmental influences. A Gut Flora Test can therefore be particularly interesting if you take medication regularly, smoke or are under stress constantly.

  • How does the Gut Flora Test work?

    To get your gut flora tested, you take a small stool sample yourself at home. To do this, use the stool collection aid and a collection spoon, both of which are included in the Gut Flora Test kit. Then send the sample in a sample collection tube to the medical laboratory using the provided prepaid return envelope.

    The medical laboratory then uses modern biotechnology to analyse the DNA of the intestinal bacteria contained in the sample and compares it with the gene sequences of known bacteria. The analysis can take up to two weeks.

    Caution: You should not do the Gut Flora Test if you suffer from diarrhoea or an acute gastrointestinal infection.

  • What do I have to bear in mind when I take the sample?

    The stool sample can be collected at the convenience of your home: simply, quickly and discretely. The Gut Flora Test kit includes detailed and illustrated instructions that explain all steps of the procedure in detail. There are a few things you need to bear in mind:

    A bean-sized sample of your stool need to be collected in the sample tube. Simply collect 3-4 small spoon with the provided spoon that you find attached to the lid of the tube. If the sample is a little larger, this is not a problem.

    The sample tube contains a DNA stabilising liquid that mixes with the stool sample and ensures that the sample remains durable for a certain time. The sample does not have to be completely dissolved in the liquid. It is sufficient if the sample and liquid mix well.

    You should in any case avoid direct contact with the DNA stabilising liquid. The liquid can irritate your skin and eyes, especially.

    Because of the DNA stabilising liquid, the sample is durable for a longer period of time, however that period is not unlimited. We recommend to send your sample to our medical partner laboratory on the day of collection by using the free return shipping.

  • What does the result report tell me?

    The results report contains your individual profile of your gut flora. This gives you a deep insight into the composition of the bacteria that colonise your intestine. The results report also compares your results with the data of a healthy comparison group.

    You will learn about your measured values: 1. species richness and diversity index: What is the diversity of bacteria that colonise your intestine? 2. Dysbiosis index: Is there an imbalance between "good" and "bad" bacteria in your gut? 3. Enterotype (intestinal type): Do you have the flora of a meat-eater or vegetarian? 4. Firmicutes/Bacteroidetes and Prevotella/Bacteroides ratio: Does your intestinal flora possibly contribute to a possible rapid weight gain? 5. Composition of bacterial strains (phyla): How are the four strains Bacteroidetes, Firmicutes, Proteobacteria & Actinobacteria distributed in your gut? Overview of all bacteria: Which functional bacteria and which species and genera occur within the bacterial strains?

    More about these results and what they mean you can find out in answers further down on this page.

  • What is the gut flora?

    Intestinal bacteria, intestinal fungi and other tiny organisms form your individual intestinal flora. Hundreds of millions of such microorganisms live in your gut - and they can grow to a total mass of 1.5 kilograms! The scientific term used today for the intestinal flora is intestinal microbiome.

    The intestinal flora performs important tasks and is closely linked to health in the whole body. The intestinal bacteria determine how your gut utilises food and how well the immune system is set up. The intestinal microbiome even impacts the brain and influences your mood and psyche.

    If the complex gut flora is out of balance, it affects the whole body. Researchers suspect that an imbalance of bacteria in your gut causes digestive problems, abdominal pain, frequent infections and exhaustion, among other things.

  • What is the purpose of the gut flora?

    Intestinal bacteria are an integral part of a healthy digestion. In addition, they contribute to a strong immune system and perform a number of other tasks. Some known tasks include the following:

    Digestion: Among other things, the intestinal bacteria produce vitamins and essential amino acids from food, as well as the so-called "butyrate", which contributes to the gut health.

    Immune system: The largest part of your immune system is located in the intestine. Therefore, the gut flora plays a major role in strengthening these defenses and keeping pathogens away. Scientific studies even suggest that a healthy gut flora can ward off allergic reactions.

    The Gut Feeling::There is probably a lot more to the term "gut feeling" than we have long suspected. Researchers have discovered that gut bacteria also communicate with the brain. That way, the gut flora probably influences feelings and moods and can even have an effect on how depression develops.

  • Why is a biodiversity of bacteria important?

    The biodiversity describes how many different types of bacteria exist in your gut flora. Simply put, the more types of bacteria, the better it is for your heath. For instance, scientists believe that a greater diversity helps prevent diseases and overweight.

    With the diversity index given in the results report you will learn whether the bacterial species in your gut are fairly evenly distributed or if certain species of bacteria predominate your bowel.

  • What is the dysbiosis of the gut?

    There are bacteria in your gut that scientists consider to be positive for your health, however there are also "bad" gut bacteria. The "good" bacteria are usually in the majority and a certain number of "bad" bacteria is still important for stimulating the immune system.

    If you are experiencing a dysbiosis, this simply means that your mircrobiome is out of balance. In this case, a proportion of "bad" gut bacteria predominates your bowel. The dysbiosis index in the results report of the cerascreen® Gut Flora Test can be used to define and determine a possible imbalance.

    Many of the "bad" bacteria are found, for example, in people who suffer from inflammatory bowel diseases, such as Crohns disease or ulcerative colitis. As a result, researchers suggest to shift the balance of bacteria in favour of the positive ones.

  • What is a gut type?

    Scientists classify the gut flora into different gut types, or "enterotypes". Which gut type you have depends on the foods that you eat. Depending on your diet, your intestines require different bacteria to make the best use of the food.

    There is a significant difference between people who consume a lot of animal fats, protein and sugar and those who eat mainly vegetarian food. The groups can be divided into these gut types:

    B-type: In the gut of people who eat a lot of meat and rather few vegetables, the bacterial strain „Bacteroides" often predominates. The gut requires these bacteria in order to make best use of meat. Bacteroidetes then produce vitamins that are rare in a meat-based diet, such as vitamin C.

    P-type:In the gut of people who consume mostly vegetables, for instance vegetarians and vegans, the „Prevotella" bacteria often predominate. These bacteria utilise dietary fibres and other carbohydrates. In that process they produce, among other things, folic acid and healthy short-chain fatty acids.

  • How does the gut flora impact the body weight?

    Scientists believe that the ratio of certain strains of bacteria influences weight gain as well as fat loss. The results report of the Gut Flora Test will give you an indication of whether possible weight problems that you experience may be related to your gut flora.

    The ratio of Bacteroidetes to Firmicutes:
    A large proportion of intestinal microbiome belong to the two strains Bacteroidetes and Firmicutes. Some scientific studies point to the fact that people in whom the firmicutes is predominant are more likely to be overweight than those who had more bacteroidetes in their gut.

    This is most likely due to the fact that Firmicutes bacteria can draw a larger amount of energy from foods - and this energy is then stored as fat cells.

    The ratio of Prevotella to Bacteroides:
    Studies show that people who have a ratio of more Prevotella bacteria than Bacteroides bacteria break down fat faster and tend to lose weight when they follow a high fibre diet.

  • Which bacteria are examined in the Gut Flora Test?

    The results report gives you measurement results for all intestinal bacteria in your gut flora.

    This includes the upper categories of the bacterial phyla, that is the four strains Bacteroidetes, Firmicutes, Protobacteria and Actinobacteria.

    With the Gut Flora Test you will also find out which functional bacteria have been detected - these include bacteria that contribute to the formation of the intestinal mucosa and those that are potentially pathogenic.

    Finally you will receive a list of all bacteria in your sample, including the various species and genera within the strains.

  • What kind of recommendations will I receive?

    The results report of the Gut Flora Test will explain how you personally can contribute to maintain a healthy and balanced gut flora in day-to-day life. Surely the most important role is that of your diet.

    A balanced diet also serves to different intestinal bacteria and can thus contribute to a diverse gut flora. Dietary fibres, secondary plant compounds and probiotics as well as prebiotics are generally positive for your intestinal health.

    A generally mindful lifestyle also has a positive effect - for example through regular exercise and a healthy body weight.

  • Who is the Gut Flora Test not intended for?

    The Gut Flora Test is not or only partially suitable for certain groups of people:

    People with infectious diseases like hepatitis and HIV may not use the Gut Flora Test.

    People with haemophilia should not take the test.

    Pregnant and nursing women should only take the Gut Flora Test under medical supervision. The given reference ranges and recommendations do not apply for people in this group; consult your medical professional for advice concerning your test result.

    The Gut Flora Test is not intended for children under 18 years of age.

    The test is not intended to diagnose illnesses or disease. For example, if you suffer from a depression or are in physical pain, consult a doctor.
