title: [Poorly tolerated or genuinely allergic? How to properly assess food allergies].
abstract: Massive immune reactions to certain foods may be traced back to immunological, but also to non-immunological mechanisms. The diagnostic work-up must therefore aim to distinguish an allergy from other inflammatory, neoplastic or immunoregulative disorders. The most common form of gastrointestinal-mediated allergy form are the IgE-mediated reactions of the immediate type (Type 1 allergy). The routine diagnostic investigation includes history-taking, a daily diary of foods eaten, skin tests and antibody determination. The diagnosis of an allergy is often complicated by the multitude of possible manifestation sites, a possibly localized effect, and variations in the depth of allergic processes. To confirm the diagnosis, an oral provocative test should always be performed.
