Proven Food-Induced Acute Urticaria and Predictive Factors for Definitive Diagnosis in Childhood

Abstract

Cow's milk, hen's eggs, and nuts were the most common allergens in the etiology of childhood food-induced acute urticaria. Although the urticaria activity score provides guidance for diagnosis, an oral food challenge is often essential for the definitive diagnosis of a patient with a history of food-induced acute urticaria.
