In order to get to the recommendations, our team of medical journalists and nutritionists examine current scientific studies.
- We scanned hundreds of studies for the symptom check and analyzed and documented more than 250 relevant relevant from them. The studies come from very different scientific journals, including renowned publications such as Nature and BMJ.
- See you whether there are verifiable connections between the symptoms and various parameters that we measure with our tests.
- We evaluate these relationships and ask questions like: How high is the quality of the studies? Did you appear in trustworthy magazines? How big was the influence on the symptom in the studies?

Histamine Intolerance Test
To the product page
Did you know that headaches, nausea, irregular heart rate, abdominal pain, gas and skin rashes as well as itching may all be signs of histamine intolerance?
Histamine Intolerance is intolerance of histamine consumed through food. It is caused by a deficiency in the histamine-degrading enzyme diamine oxidase (DAO) or by an imbalance of histamine and DAO. As far as experts are concerned, it is not normally caused by genetic factors; it is often known to be associated with another health condition.
With the cerascreen® Histamine Intolerance Test, you can determine the concentration of the enzyme diamine oxidase (DAO), which breaks down histamine in your intestine, in your blood with a blood sample. A low value of DAO can confirm histamine intolerance. You will receive a results report with information and recommendations on how to follow a low-histamine diet and boost your intestinal health.
Lactose intolerance is the most common food intolerance worldwide - in large parts of Africa and Asia, the majority of people cannot tolerate lactose. In the United Kingdom, studies show that eight per cent of the population is affected. They suffer from symptoms such as abdominal pain, nausea, flatulence and diarrhea when they eat foods containing lactose.
With the cerascreen® Lactose Intolerance Test, you can determine the concentration of hydrogen and methane in your breath after consuming a lactose solution. Your values from the test are then able to provide you with an indication of a possible lactose intolerance.
What is lactose intolerance?
Lactose intolerance is an intolerance to disaccharide (polysaccharide) lactose or milk sugar. This consists respectively of a molecule of the monosaccharides glucose and galactose. Lactose has to be split into its monosaccharides for processing in the small intestine. The enzyme lactase, which is found in the villi of the small intestine, is responsible for this function. Only the monosaccharides can be metabolised by the sodium dependent SGLT1-transporter in the various sections of the intestine. Depending on the residual activity of the enzyme lactase, the degree of severity of lactose intolerance can differ greatly and the symptoms vary correspondingly. If the milk sugar is not or only partly split by the digestive enzyme lactase, and if larger amounts of milk sugar reach the lower sections of the intestine populated by bacteria, the lactose then feeds the bacteria. This creates large amounts of gases and fatty acids, which leads to complaints. Lactose intolerance should not be confused with a milk protein allergy. In contrast to an allergy, in which the immune system is involved and the corresponding antibodies are formed, lactose intolerance arises from a deficit or insufficiency of enzyme production without the involvement of the immune system. Approximately 15-20 % of the total population in Great Britain is affected by lactose intolerance. There is a North-South divide in Europe.
Which complaints can occur from a lactose intolerance?
If the milk sugar is not or only insufficiently split by the digestive enzyme lactase in the small intestine, larger amounts of the undivided lactose reach the lower sections of the intestine populated by bacteria and ferment there. Large amounts of hydrogen, methane, carbon dioxide and short-chain fatty acids are subsequently created, which leads to complaints. Neither the hydrogen nor methane but rather the formation of carbon dioxide and fats are what cause symptoms. The large amount of carbon dioxide causes flatulence. This can be eliminated via the large intestine. In contrast, in the small intestine the gas is transported through the intestinal wall, passes to the blood and is expelled through the lungs. This procedure is extremely uncomfortable and can also cause bad breath. The fatty acids carry water into the intestine, which causes a dilution of the stool and leads to diarrhoea. Bowel sounds are caused by the increase in intestinal movement. The change in consistency of the stool is explained by the increase in proportion of fatty acids, so-called fatty stools, or the increased inclusion of gases. Other symptoms are possible in connection with lactose intolerance. These include heartburn and fatigue as well as migraine headaches.
Food Allergy Test
To the product page
Are you possibly allergic to food? This question is not always easy to answer. Severe allergy sufferers have often reacted to peanut, soy, fish, etc. with clear symptoms since childhood, but for some people, allergies develop over the course of their lives, and the signs are less clear. In everyday life, however, this can become uncomfortable and restrictive, with symptoms such as skin rashes, gastrointestinal problems or a sore throat.
The cerascreen® Food Allergy Test helps you investigate such hidden allergies. The send-in blood-sampling kit that you can use at home determines the concentration of specific IgE antibodies in your blood. This analysis provides first indications of a possible food allergy. For a definitive allergy diagnosis, discuss the results with your doctor.
Gut Flora Test
To the product page
With the cerascreen® Gut Microbiome Test, a diagnostic sample-taking and send-in test that you can use at home, the composition of the bacteria in your intestine can be determined. In a laboratory, the DNA of the intestinal bacteria is analysed using state-of-the-art biotechnology. With the results report, you will gain comprehensive insights into your microbiome, also called gut flora: from the variety of bacterial species to the balance between good and bad bacteria as well as the breakdown of all strains and types of intestinal bacteria.
If you suffer from symptoms such as bloating, diarrhoea, stomach pain, nausea, bloating and dizziness, you may be suffering from fructose intolerance. This intolerance is triggered by fructose, which is mainly found in certain types of fruit and vegetables, fruit juices, honey and many sweets.
With the cerascreen® Fructose Intolerance Test, you can determine the concentration of hydrogen and methane in your breath after consuming 420 millilitres of apple juice. High gas values indicate a possible fructose intolerance.
