[Allergy assessment: when and how?].

Allergy assessment: when and how? Abstract. Allergies are common in the clinical practice. The most important allergens are pollen, house dust mites, animal dander, mold and allergens attributable to a particular work environment. The medical history is a very important part for diagnosing an allergy, because sensitizations detected by skin prick tests and laboratory tests are common but not always symptomatic and therefore without clinical relevance. There are 3 options to manage allergic diseases: avoidance of allergens, symptomatic treatment and - in selected cases - a causal treatment like allergen-specific immunotherapy.
