Test for food allergy

A referral from your physician or specialist and an appointment is required before arriving at the allergy outpatient clinic.

Attention: We only test for food allergies. We do not conduct lactose and fructose intolerance tests and do not test for  histamine intolerance.

1. Medical consultation

You tell the doctor about your health complaints and especially under what circumstances you experience them (for example, especially in the morning or always at the same time of year). The test programme is drawn up based on this medical consultation and according to the examinations requested by the referrer. The test usually consists of:

2. Blood sample

Because food allergies represent an immune reaction to plant or animal protein components, the antibodies developed in this process can be determined in a blood sample. For years now, a component-based diagnosis (determination of various allergens of an allergen source) for the risk assessment of severe reactions can also be performed. The laboratory examination of the blood sample usually takes a week.

3. Skin testing

Here a selection of test substances with allergy triggers is dripped onto the skin, and then the uppermost layer of skin is punctured through the drops with a lancet. This process is virtually painless. In a positive test reaction (= allergy) an itchy wheal similar to a mosquito bite will form on the skin. In some cases several skin testing appointments may be necessary.

The outermost layer of the skin will be pricked by a lancet through a drop of an allergy trigger, e.g. a pollen extract.

If the test turns out to be positive (= allergy), an itchy wheal accompanied by localised redness and swelling will form.

4. Medical consultation

After completion of all examinations, you will receive a report containing all tests and their results. The diagnostic findings will be given to you by a doctor and explained. If necessary, a therapy proposal will be offered.

Time required for the allergy test: usually 2 times 1 hour (including waiting times).
