Test de provocation par voie orale aux aliments chez l'enfant. Quand, pour qui et comment? Sélection des patients

Oral food challenge (OFC) is the gold standard to diagnose food allergy. The OFC defines also the tolerance to a particular food in a child previously sensitized or allergic. There are significant risks associated with OFC. According to the literature review and for the three major foods implicated in food allergy in children (cow's milk, hen's egg and peanut), this chapter analyzes the indications, taking into account the clinical situation and the results of allergy testing (specific IgE assay, skin prick tests, atopy patch tests), and the contra-indications of OFC.
