Because egg yolks are less allergenic than egg whites, we performed an oral food challenge with heated egg yolk slightly contaminated with egg white (EYSEW OFC) in infants allergic to hen¡¯s egg. We hypothesized that the EYSEW OFC results would predict the egg allergy¡¯s natural course %K Challenge test %K Egg allergy %K Food allergy %K Specific IgE %K Prognosis %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5053340/
