The diagnosis of food allergy (FA) belongs, despite several diagnostic possibilities, to the most complicated parts of paediatric allergoimmunology and gastroenterology. Clinical diagnosis is done on the basis of results of particular standardized diagnostic methods in vivo or in vitro. FA should have immunological background and the task of the specialist is to verify it. Diagnostic algorithm of FA consists of detailed personal and family history, careful physical examination and of several standardized tests: skin prick tests, atopy patch tests and evaluation of food-specific IgE. According to the results of these procedures we can establish diagnostic elimination diet (dechallenge) for certain period of time which should be followed by oral food challenge. Finally, according to the results of food challenge we can definitely confirm or exclude the diagnosis of food allergy.
