Adverse Food Reactions (AFR) include both food allergies and food intolerances. They can present as pruritic skin disease, ear disease and/or as a gastrointestinal issue.
Elimination diet trials are the only accepted method to reach a definitive diagnosis of an AFR, including food allergy. However, the role of food-specific IgE and IgG antibodies in the diagnostic work-up of AFRs is now increasingly accepted.
