An accurate medical history is essential for the diagnosis of food allergy, in particular should be investigated a framework compliant with food allergy and a temporal relationship between the introduction of food and the appearance of symptoms. The presence of skin test (prick test) and/or positive serum specific IgE against foods indicates only a sensitization, condition that can be compatible with the intake of a food. For a correct diagnosis of food allergy an oral food challenge test must be provided (if the history and skin prick tests/specific serum IgE are not exhaustive for diagnosis).
