Which test is right for me?

Allergy, intolerance, deficiency, incompatibility… How are you supposed to find your way around? We have the solution: To help you find the right test, we have put together some helpful guidelines. So you can quickly find out what the possible causes for your complaints are and start your way to recovery.

Symptoms: When & Which?

For the right test selection, it is especially important to listen to your body. If you can determine approximately when which symptoms occur, this can narrow down the possible causes very well.

To determine when symptoms appear, count the time from the moment the “troublemaker” was ingested by you (eating, inhalation or skin contact) until the symptoms appear.

When do symptoms occur?Immediatelyafter 30-120 minutesafter 6-72 hoursgeneral, non-specific
Possible causeAllergyIntoleranceIncompatibilityDeficiency
What are the possible symptoms?Itching
Skin rashes
Respiratory problems
irritated mucous membranes
abdominal pain
foul-smelling flatulence

Abdominal or stomach pain
(chronic) fatigue
Atopic dermatitis flare-ups
Skin rashes
Depending on the deficiency:
bad mood
Decreased performance and concentration

The longer it takes for symptoms to appear, the more difficult it is to establish a connection. In addition, there are different types of allergies, intolerances, etc., which on the one hand make a determination even more complicated, but on the other hand can better narrow down the search for the cause.

An allergy is an overreaction of the immune system to certain protein components (of food, pollen, etc.) Actually harmless substances are perceived as a danger and the immune system forms antibodies. This defensive reaction to allergens (this is the name given to the substances from the point at which they cause problems) in turn leads to symptoms.

Depending on where allergens enter the body, the symptoms can differ. If they are inhaled with pollen or particles from animal fur, there is increased irritation of the mucous membranes in the face. In the case of food allergies, there are also digestive complaints (nausea to vomiting).

Typical allergies

Allergy testing usually involves testing several allergens at the same time that belong to the same “category”. Common allergies include:

  • Food allergy
  • Animal hair allergy
  • Pollen allergy
  • Mite allergy

Intolerances are only mentioned in connection with food. Complaints then occur shortly after consumption because the body has problems with properly utilizing or transporting components. The remains of the food are broken down in the intestine by bacteria. This results in gases, flatulence, diarrhea and cramps, among other things.

In addition to lactose or fructose intolerance, where the narrowing down of possible foods is still relatively simple, there is also histamine intolerance. Histamine is contained in very many different foods, which at first glance have nothing to do with each other. Typical foods that cause problems in histamine intolerance are, for example, tomatoes, long-aged cheese, sausages or citrus fruits.

Test intolerances


Intolerance to food is caused by an above-average reaction of the immune system to protein components. Due to a weakened and permeable intestine, disturbing substances enter the bloodstream, against which the body reacts with defense substances (IgG-4 antibodies). Like intolerances, intolerances refer only to food.

Test incompatibilities

Symptoms of intolerance are often not very intense and appear rather gradually, depending on the amount of the intolerant food. Therefore, the diagnosis is usually very difficult. To facilitate the diagnosis, intolerance tests offer simultaneous testing for several foods.

With the kiweno intolerance test (currently only available in Austria), over 70 foods are tested with just a few drops of blood.


Deficiency symptoms of certain nutrients occur when the supply cannot cover the demand in the long term. The reasons for this can be very diverse: unbalanced diet, lifestyle, digestion, and much more. Since the symptoms of deficiency symptoms come very insidiously and are often subliminal, they are not directly associated with a possible deficit. All too often, lack of drive, constant fatigue or headaches are dismissed as everyday complaints and not questioned further.

Common nutrient deficiencies

  • Vitamin D
  • Iron
  • Vitamin B12
  • Omega-3
  • Magnesium
