The anamnesis requires from the treating physician beside large experience, a profound allergological knowledge, whereby in particular the estimation of the allergen exposure requires special knowledge. Continuous further training and information form the basis for this.

From the examination of the upper airways (nose and throat), the conjunctiva via the lungs to the professional examination of the skin, all results are taken into account.

Complex skin tests as well as a thorough blood test give indications of possible sensitisations.

If the aforementioned diagnostic methods do not produce clear or contradictory results, a provocation test is carried out for definitive clarification. The suspected allergen is applied and any organ reactions measured.
