Egg allergy is one of the most common food allergies in childhood.Previous studies have shown that allergy tests currently used in clinical practice, such as skin prick test (SPT) and specific IgE (sIgE) to allergen extracts, are not very precise predictors of the allergic status to BE, with sensitivity and specificity being 54/68% and 80/74% respectively, according to a recent meta‐analysis.We aimed to assess accuracy of new diagnostic tests, namely the basophil activation test (BAT), as well as current tests, such as SPT and sIgE, compared to DBPCFC to BE and to lightly cooked egg (LCE). The BAT assesses the expression of activation marker CD63 on the surface of blood basophils by flow cytometry following stimulation with the allergen or controls.
