Allergy testing in children can be reduced, since it should have no consequences in most cases of asthma and allergic rhinitis. In atopic dermatitis, it should be done, only when food allergy is suspected. Food allergy must be confirmed by provocation except from allergy to peanuts, which may be diagnosed by component resolved testing. Screening with skin prick test or specific immunoglobulin E is meaningless, since it reveals different results and in most cases tests for, what is consumed without reactions. In our opinion provocation with penicillin can be done without prior testing in case of suspected allergy.
