Allergies and intolerances
Do you suffer from recurring issues such as digestive problems, skin irritations, or breathing difficulties and don't know why? It could be an allergy or food intolerance behind it.
By the way: Intolerance and sensitivity mean the same thing – both terms describe the body's difficulty in properly processing certain foods. Our comprehensive tests help you find the cause and pave the way to a symptom-free life.
The best source for more information on the topic of allergies is the German Allergy and Asthma Association.
Key Messages
💡 Symptoms such as skin irritations or digestive problems can be indicators.
💡 Blood tests reveal allergic reactions and intolerances.
💡 Results help to avoid triggers and alleviate discomfort.

What are allergies?
Allergies are overreactions of the immune system to essentially harmless substances, known as allergens. These can be found in foods, pollen, animal hair, and much more. Your body mistakenly identifies these substances as a threat and reacts with symptoms such as sneezing, itching, rashes, breathing difficulties, or in rare cases, even dangerous allergic shocks.
Common allergens:
- Pollen
- House dust mites
- Animal hair
- Foods like peanuts, milk, or eggs

What are food intolerances?
In contrast to allergies, intolerances are sensitivities where the body has difficultyprocessing certain substances. The immune system is not involved in this case; instead, enzymes necessary for the breakdown of certain foods are often lacking. Symptoms often appear with a delay and usually manifest as digestive problems such as bloating, diarrhea, or nausea.
Typical food intolerances:
- Lactose intolerance
- Fructose intolerance
- Histamine intolerance
The difference between allergies and intolerances
While in the case of an allergy the immune system becomes active and immediately causes symptoms, an intolerance is a reaction to the lack of availability of enzymes or other metabolic processes in the body. Allergies can potentially be life-threatening, while intolerances are generally not dangerous but still very unpleasant and significantly affect the quality of life.
Allergies:
- Involvement of the Immune System: In a food allergy, the immune system mistakenly reacts to a harmless food as a threat and releases antibodies to combat the perceived allergen. This can lead to an immediate reaction.
- Rapid Symptoms: Symptoms usually occur within minutes to hours after consumption and can trigger skin rashes, breathing difficulties, swelling, gastrointestinal issues, or even life-threatening reactions such as an anaphylactic shock.
- Small Amounts are Sufficient: Even a very small amount of the allergen can provoke a strong reaction.
Incompatibilities or intolerances:
- No immune reaction: An intolerance is not triggered by the immune system but occurs because the body cannot properly digest or process certain components of foods. Often, necessary enzymes are lacking.
- Delayed symptoms: The symptoms often appear delayed, sometimes only hours after consumption, and usually affect the digestive system (bloating, diarrhea, abdominal pain). They are unpleasant but rarely dangerous.
- Quantity-dependent: Symptoms often only occur when a larger amount of the food has been consumed.

Why should I take an allergy and intolerance test?
Many people suffer for years from unclear symptoms without knowing that allergies or intolerances could be the cause. A targeted test provides clarity and helps you identify and avoid the triggers.
- Targeted Treatment: With a clear test result, you can specifically avoid the triggers and alleviate your symptoms.
- Improve Quality of Life: Find out which foods or environmental factors harm you to live carefree again.
- Avoid Dangerous Reactions: Especially with allergies, quick action can be life-saving, particularly in severe reactions like an anaphylactic shock.
