Luminex-based Assay to Identify Major IgE-binding Episode Among IgE-mediated Wheat-allergic Patient

Blood drawn will be done once using 15 mL of blood volume (Serum or plasma samples will be collected during the routine follow up of level of sIgE to wheat or during the oral food challenge test which intravenous insertion routinely prepared in case of the emergency reaction occurred). The specimen will be transferred to the Icahn School of Medicine at Mount Sinai, New York, USA for Laboratory processing (Luminex-based peptide assay)
