Predictive values of egg‐specific IgE by two commonly used assay systems for the diagnosis of egg allergy in young children: a prospective multicenter study

摘要

BackgroundSpecific IgE (sIgE) is often used to predict oral food challenge (OFC) outcomes in food allergy, but interpretation of the results may vary depending on the assay method employed and the patient population tested. The aim of this study was to use two commercial assay systems to determine egg‐sIgE values predictive of allergy within the most common populations treated at pediatric clinics.
