A) One little blood tube: In your first visit in AllergyCare® we will take blood from your vene. Your blood serum will be tested in the latest allergen macroarray available: on the ALEX® test 282 allergen molecules and extracts are spotted, comprising the most important pollen, house dust and food allergens, and many more. Please contact us prior a visit with children younger than 10 years.

B) If among the hundreds of allergens one allergen (BLUE) binds IgE immunoglobulins (RED) from your blood serum the bound IgE can be visualized by a detection system (YELLOW) in the laboratory. The more IgE you have in the blood and binds the allergen, the higher is the signal.

C) Technically the strength of the signal can be translated into false colours. The more IgE you have the lighter the spots and the higher the risk for clinical allergy. The test results can be mailed to you, but we strongly recommend to take a second appointment, usually one week later. In the follow-up visit, results will be interpreted and specific measures initiated against your allergy.

D) The allergen macroarray helps to detect crossreactivity. For instance, IgE to birch pollen may also cross-react to similar molecules in apple, carrot, hazelnut and other allergen sources. Besides the pollen allergy you may then experience sensations in mouth or lips when eating an apple or hazelnut. The test result enables a reisk assessment, which is important especially in regards to food allergy being potentially dangerous.
