Do not perform allergy tests for drugs (including anhestetics) and/or foods when there are neither clinical history nor symptoms suggestive of hypersensitivity reactions
Do not perform the so-called “food intolerance tests” (apart from those which are validated for suspect celiac disease or lactose enzymatic intolerance)
Do not perform serological allergy tests (i.e.: total IgE, specific IgE, component-resolved diagnosis) as first-line tests or as “screening” of inhalant & food immediate hypersensitivity assays
Do not treat patients sensitized to allergens or aptens if there is not a clear correlation between exposure to that specific allergen/apten and symptoms suggestive of allergic reaction. This recommendation is particularly strong for allergen immunotherapy and elimination diets
Do not diagnose asthma without having performed lung function tests (including bronchodilating test and/or bronchial challenge)
