Are you 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 in the course of life 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 to 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.
- safe and easy to perform at home
- certified laboratory analysis after a few days
- medically established measurement of IgE antibodies
- directly implementable recommendations + tips
- receive your results within 2-3 business days after sample arrival

Questions about food allergy
Why test for a food allergy?
Some people suffer from food allergies - 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 orientation with a test, which you might not be able to tolerate.
In theory, you could be allergic to all kinds of foods. In practice, however, it is always the usual suspects that are responsible for a large part of the allergies. These common food allergy triggers- and a few more - are taken into account in the cerascreen® Food Allergy Test.
If you can use the test to find out a previously undetected food allergy, it is important to remove the food from your menu. 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 Allergy Test work?
For the food allergy 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.
In the next step, you send the sample to a diagnostic laboratory. The laboratory analyzes the amount of certain IgE antibodies in your blood. These antibodies indicate whether there is sensitization to one of 38 different foods. After the evaluation, 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 result report of the Food Allergy Test shows for which foods there are large amounts of IgE antibodies in the blood. A clear table shows you how strongly you are sensitized to 38 different foods and food groups
This sensitization shows how high the potential of your immune system is to react to food with allergic reactions. It is therefore a first indication of a possible food allergy.
The test cannot give you a definite allergy diagnosis. The diagnosis may only be made by doctors who combine an allergy test with a medical history, i.e. question you about your symptoms and your state of health. 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 no longer have to carry out skin tests or blood tests.
What recommendations do I receive?
You will receive recommendations on how to deal with the test result. It is important that you take into account whether you have any symptoms after eating certain foods. It happens that people have an increased number of IgE antibodies against a food in the blood, but still show no symptoms. In this case too, you will receive recommendations for action in the results report.
You will also receive recommendations on how to deal with identified allergies and how to make your diet healthy and balanced despite a potential food allergy. We give specific tips that you can use to support your digestion and intestinal health.
How common are food allergies?
According to estimates by the German Nutrition Society, three to four percent of adults in Germany have a food allergy.
Allergies to food are somewhat more common in children, and in many cases they go away on their own until adolescence or adulthood.
Which types of allergies will be tested?
There are different types of allergies. By far the most common type is type 1 allergy, also called immediate type allergy. Food allergies generally fall into this category.
These type 1 allergies are associated with increased concentrations of IgE antibodies. The cerascreen® Food Allergy 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 are IgE antibodies?
Antibodies are one of the defense mechanisms of your immune system. These are certain proteins. The body uses them primarily to switch off pathogens such as viruses and bacteria. There are different classes of antibodies, each with different tasks. The immunoglobulins E (IgE) specialize in the defense against parasites, for example worms.
When your body's immune cells recognize pathogens or parasites, they pass this information on to plasma cells, a class of white blood cells. These then produce specific antibodies. "Specific" means that these antibodies are only there to initiate reactions against a specific pathogen.
How are IgE antibodes and allergies related?
If you have an allergy, your body has confused a harmless substance with a threatening pathogen in the past. Substances that can be used are proteins (proteins) that are found in foods, pollen, animal hair, dust mites and medicines, among other things. These possible allergy triggers are called allergens.
Your immune system produced certain IgE antibodies to the allergen after this mix-up. If the same substances hit the body again, your immune system will sound the alarm. They initiate defense reactions: the messenger substance histamine is released, inflammation occurs and thus the typical symptoms of an allergy.
The IgE antibodies can stay in your body for your whole life. In some cases, the allergies disappear. In the case of food allergies, sensitization usually begins in childhood. As teenagers, many then lose their allergies to cow's milk, eggs, wheat and soy. Allergies to nuts, fish and shellfish, in turn, persist in most cases for the rest of life.
What are the symptoms?
The food allergy is an allergy of the immediate type. The symptoms usually appear immediately or only a few minutes after eating.
Typical symptoms of a food allergy are:
- Rashes and redness of the skin
- Gastrointestinal complaints such as diarrhea, vomiting and abdominal pain
- Itchy palate and "furry feeling" on the tongue
- Difficulty to breathe to allergic asthma
- Rashes and redness of the skin
What is the anaphylactic shock?
In particular, nuts, soy and animal foods such as milk, egg and shellfish can also cause a dangerous allergic shock (anaphylactic shock). The blood pressure suddenly drops. This can lead to fainting and in rare cases even death.
If you have ever had anaphylactic shock or you have been found to be at risk, doctors will prescribe an anaphylaxis emergency kit. This includes medicines that you can use to counteract this violent allergic reaction. Most importantly: an Epi-Pen (epinephrine pen) that allows you to inject adrenaline into the thigh, which usually prevents the drop in blood pressure.
Which foods trigger food allergies?
More than 170 foods can be responsible for allergies. However, a far smaller number of foods is by far the most frequently responsible. They include:
- Cow's milk and eggs
- Legumes (especially peanuts and soy)
- Fish and seafish
Allergies to various types of fruit, vegetables, spices and meat are somewhat less common.
What can I do about a food allergy?
There is no therapy to cure food allergy. In some cases, allergies resolve on their own over time. Doctors still have no way of influencing this effectively.
The only effective long-term measure is therefore to avoid food that you cannot tolerate. This can mean that you have to spend some time studying ingredient lists on packaging. Many products contain allergens that you would not expect in them. Soy, egg, milk and wheat in particular are found in numerous finished products and processed foods.
Fortunately, manufacturers have to label and highlight the 14 most important allergens on their products. And restaurants and bakeries must also give you information.
Are there medications for food allergy?
Medications only help with food allergies to suppress the symptoms. Antihistamines can temporarily alleviate allergic symptoms. These drugs are the same that are used for hay fever. However, they are not suitable for long-term use.
People who have particularly severe allergic reactions often carry an anaphylaxis emergency kit with an adrenaline injector ("Epi pen"). The set can be life-saving for you if you are experiencing anaphylactic shock.
Who is the test not suitable for?
The Food Allergy Test is not suitable or only suitable for certain groups of people:
- People with contagious diseases like hhepatitis are not allowed to take the Food Allergy Test
- People with the Hemophilia blood disorder should not take the blood test
- Pregnant and 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 result 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 diarrhea or extreme pain, contact a doctor.
