Oral food challenge (OFC) is a procedure that is conducted most commonly by allergist/immunologists in their office or in food allergy centers to confirm a food allergy or to confirm tolerance to the food. The procedure as conducted in clinical practice is mostly open food challenge and, in research, a double-blind, placebo controlled food challenge. OFC has associated risks that can be minimized by having the challenges conducted by trained personnel who are prepared to treat allergic reactions and who have rescue medications available. However, OFCs have tremendous benefits to the patients and their families, including the potential to determine that a food is no longer an allergen and can be introduced into the diet. Even OFCs that result in clinical reactions have the benefit of confirming the food allergy and demonstrating the therapeutic effect of the rescue medications. The study of the outcomes of OFC has shed light on food allergy reactions and characteristics of the patients with food allergy as well as on the value of other diagnostic tests compared with OFC. OFCs have helped establish food allergy thresholds, confirm that subjects enrolled in research studies have the allergy, and demonstrate the response to the therapies tested in terms of ameliorating the allergic response or raising the reaction threshold. OFCs have also been used to promote the recent guidelines for the prevention of peanut allergy by identifying the infants at risk for peanut allergy but who are not allergic yet.

Hen’s egg, as one of the most common reasons for IgE-mediated food hypersensitivity, affects both children and adults. Taking precautionary measures is suggested for the consumption of other birds’ eggs for patients with allergy to hen’s egg. This paper describes a rare patient with quail egg allergy, which manifested no allergic reactions after oral food challenge with hen’s egg white
