Online health + nutrition coaching + Food Reaction Test


There are countless different food allergies and intolerances and almost as many tests to get to the bottom of them. Do you have unexplained symptoms and don’t know where to start? Then the cerascreen® Food Intolerance Test can offer you a good initial indication of which foods you may not be able to tolerate. Our offer includes the Food Intolerance Test as well as nutritional coaching.

With our home send-in kit, you can quickly and easily determine whether your body creates antibodies to the foods that trigger the majority of allergies and intolerances – with just a small blood sample. In the subsequent 30-minute consultation, we discuss your results with you and help you optimise your diet.

  • Collect your sample easily and conveniently at home
  • Have your sample analysed in a certified medical laboratory (according to ISO 13485 and 9001 standards)
  • Receive information on specific IgE and IgG4 antibodies* found in your blood
  • Receive a 30-minute consultation with a nutritionist
  • Get your results within 1 to 2 working days after the sample’s arrival in the laboratory

An increased number of antibodies does not mean that you have a food allergy or food intolerance. The test provides you with an initial indication of which potential intolerances you can investigate further. For a definitive diagnosis, you can clarify possible allergies with a doctor. The fact that a higher concentration of specific IgG4 antibodies is related to food intolerance is a topic of debate.

Indications of a possible food allergy

IgE is a special class of antibodies that recognises foreign and hostile substances and prevents them from entering the body. It therefore triggers reactions that make it more difficult for these substances to enter the body. This leads to inflammation, which in turn can result in typical allergy symptoms.

Symptoms such as digestive problems, skin rashes and an itchy throat can be an indication of a food allergy, together with an increased concentration of specific IgE antibodies.

This is also how doctors make a diagnosis, in two steps: they measure a possible sensitisation – that is, elevated levels of IgE antibodies, by skin prick or blood test. In addition, a doctor records the patient’s medical history by asking the patient about their symptoms and state of health.

The cerascreen® Food Intolerance Test covers the first step of this background research. It makes it possible to determine sensitisation to a food by detecting IgE antibodies in the blood.

Only doctors are allowed to make a confirmed diagnosis of an allergy. If you want to be sure, discuss the results of your antibody analysis with your doctor.

Advantages of the Food Reaction Test

Food intolerances or allergies can not only be responsible for gastrointestinal complaints. They often manifest themselves through symptoms such as tiredness, skin irritation and a burning sensation in the oral cavity. Without a food intolerance test, it is often difficult to identify the causes of such symptoms in everyday life.

To take the cerascreen® Food Intolerance Test there is no need for you to visit your general practitioner, drive to a clinic or wait for an appointment. To collect the sample, you will receive detailed, illustrated instructions, and after the analysis, you will be provided with a detailed overview of the concentration of antibodies to certain foods.

Benefit from our expertise: cerascreen® is the market leader in Europe for medical sampling and send-in kits, with eight years of experience in the development and evaluation of tests. We have developed more than 50 approved send-in test kits (medical products), analysed 250,000 samples and serve 19 countries.

The cerascreen® Food Intolerance Test – body science made easy

What happens to our body with an intolerance? And what exactly is tested? The immunoglobulins IgE and IgG4 are responsible for an allergic reaction or the typical symptoms of an intolerance. These are the gatekeepers of the immune system. They ward off substances in our body that are recognised by our immune system as particularly harmful. When you have an intolerance, your body overreacts to substances/foods that are actually harmless.

The IgE antibodies try to impede supposedly harmful foreign bodies from entering the body, triggering an overreaction. This overreaction can be characterised by typical symptoms, such as tears, sneezing, diarrhoea, redness, cramps, etc. The IgG4 antibodies want to remove foreign bodies that have already entered the body.

The IgG4 antibodies want to block or destroy the foreign bodies that have already entered the body by setting off a defensive and inflammatory reaction. We do not perceive these reactions to be as strong as the reactions caused by the IgE antibodies, but over a longer period of time, they can still cause chronic complaints and long-lasting damage.

Questions about the Food Intolerance Test and nutritional coaching

  • Why test for a food intolerance?

    Some people suffer from food intolerances – often without knowing it. In some cases, the symptoms are annoying and unhealthy in the long run, but they are also subtle and difficult to attribute to specific meals. It can then make sense to get a first indication with a test to identify which foods you might not be able to tolerate.

    In theory, you could be intolerant to all kinds of foods. In practice, however, it is always the usual suspects that are responsible for a large part of intolerances. These common food intolerance triggers – and a few more – are taken into account in the cerascreen® Food Intolerance Test.

    If you can use the test to find out a previously undetected food intolerance, it is important to remove that food item from your diet. This is more difficult with some foods than with others. Either way, you can avoid the cause of your complaints in the future.

  • How does the Food Intolerance Test work?

    For the Food Intolerance Test, take a few drops of blood from your fingertip with one of the two lancets. Everything you need is included in the test kit.

    The next step is to send the sample to a diagnostic laboratory. The laboratory analyses the amount of certain IgG antibodies in your blood. These antibodies indicate whether you are intolerant to one of 38 different foods. After the analysis, you will receive a notification and can access your personal results report via the online customer area or the My cerascreen® app.

  • What does the results report tell me?

    The results report of the Food Intolerance Test shows for which foods there are large amounts of IgG antibodies in the blood. A clear table shows you how strongly you are intolerance to 38 different foods and food groups

    The test cannot give you a definite intolerance diagnosis. However, you can use the results as a first point of reference to discuss a further course of action with your doctor, who may then carry out further tests.

  • Which recommendations will I receive?

    You will receive recommendations on how to deal with the test results. It is important that you take into account whether you have any symptoms after eating certain foods. Some people have an increased number of IgG antibodies against a certain food in their blood, but still show no symptoms. If this is the case for you, you will receive recommendations in the results report.

    You will also receive recommendations on how to deal with identified allergies and intolerances and how to make your diet healthy and balanced despite a potential food intolerance. We give specific tips that you can use to support your digestive and intestinal health.

  • Which types of allergies and intolerances will be tested?

    There are different types of allergies. A type 1 allergy, also called immediate-type allergy is by far the most common type. Food allergies generally fall into this category.

    These type 1 allergies are associated with increased concentrations of IgE antibodies. The cerascreen® Food Intolerance Test examines precisely these concentrations in response to 38 different foods. This will give you first indications of a possible allergy of the immediate type.

  • What do IgE and IgG mean?

    Immunoglobulins E (IgE) and immunoglobulins G4 (IgG4) are two types of antibodies. They belong to the defence mechanisms of your immune system. Both IgE and IgG4 represent groups of specific antibodies – that is, antibodies that are specialised in defending against very specific foreign bodies.

    If you have an allergy, specific IgE antibodies are found too frequently in the body. They trigger an immune system reaction when harmless proteins – for example from pollen, animal hair or food – enter the body. The messenger substance histamine is then released, leading to inflammation and the typical allergy symptoms.

    IgG4-mediated food intolerance is an alternative medical theory that is currently not supported by scientific studies. According to the theory, an increased number of specific IgG4 antibodies leads to defensive and inflammatory reactions. The symptoms are usually delayed – up to hours or days after you have eaten the food in question.

  • Which foods trigger reactions?

    More than 170 foods can be responsible for allergies. However, a far smaller number of foods is most frequently responsible. They include:

    • Cow’s milk and eggs
    • Legumes (especially peanuts and soy)
    • Nuts
    • Wheat
    • Fish and shellfish

    Allergies to various types of fruit, vegetables, spices and meat are somewhat less common.

  • What are IgG4 intolerances?

    According to an alternative medical theory, high concentrations of specific IgG4 antibodies are a sign of an intolerance to certain foods. According to this theory, inflammatory reactions occur in the gut after the consumption of food.

    This link between the concentration of IgG4 antibodies and the presence of food intolerances is currently the subject of scientific controversy.

  • What are symptoms of IgG4 intolerances?

    IgG4 intolerances may only appear hours or even days after you have eaten the food in question.

    Possible symptoms of food intolerance:

    • Gastrointestinal discomfort, especially flatulence
    • Headaches and migraines
    • Lassitude
    • Whistling breath sounds and running nose
    • Skin rashes
  • How can I treat a food allergy or intolerance?

    There is no treatment to cure an allergy or intolerance to food. IgG4-mediated intolerances may subside once you have avoided the trigger for a while.

    Currently, the only effective way to combat food allergies and intolerances is to recognise the reactions and avoid the foods in question.

    If you have a food allergy, medication (antihistamines) can relieve the symptoms in the short term if you have consumed an allergen. People who have particularly severe allergic reactions often carry an anaphylaxis emergency kit with an EpiPen, which they turn to in cases of anaphylactic shock

  • Who is the test not suitable for?

    The Food Allergy Test is not suitable for or is only suitable for certain groups of people:

    • People with contagious diseases, like hepatitis, are not allowed to take the Food Allergy Test.
    • People with a haemophilia blood disorder should not take the blood test.
    • Pregnant and/or breastfeeding women should only carry out the Food Allergy Test under medical supervision. The reference values and recommendations do not apply to them, so they should obtain recommendations on the test results from their doctor.
    • The Food Allergy Test is not suitable for children under the age of 18.

    The test is not there to diagnose diseases. For example, if you suffer from chronic diarrhoea or extreme pain, contact a doctor.
