Egg is one of the most important allergens in childhood feeding, and egg allergy can pose quality-of-life concerns. A clear clinical history and the detection of egg white-specific immunoglobulin E (IgE) will confirm the diagnosis of IgE-mediated reactions. Non-IgE-mediated symptoms, such as those of eosinophilic diseases of the gut, might also be observed. Egg avoidance and education regarding the treatment of allergic reactions are the cornerstones of management of egg allergy. This article discusses epidemiology, risk factors, diagnosis, treatment, and natural history of egg allergy.
