Of cross-reactivity include mammalian milks, eggs, fish, and shellfish. Examples of food families with high rates Protein stability, abundance) and patient-specific factors (immune response, augmentationįactors) that determine clinical relevance. The optimal approach to patients requires an understanding of the epidemiology ofĬlinically relevant cross-reactivity, as well as the food-specific (degree of homology, Molecular diagnostics have improved our ability to identify clinically relevant cross-reactivity, However, many are sensitized to foods without exhibiting clinical reactivity. Having allergic sensitization (positive tests) to many biologically related foods. The diagnosis and management of food allergy is complicated by an abundance of homologous,Ĭross-reactive proteins in edible foods and aeroallergens.
