Food allergies are a major public health issue affecting an estimated 8% of U.S. children, and possibly up to 10% of adults. Thirty-two (32) million patients have food allergies in the US alone and no cure currently exists. This study is a biorepository (large collection) of samples from patients with a physician-diagnosed and/or an oral food challenge-confirmed food allergy. The repository is potentially a rich resource for advancing the field of food allergy. This study aims to collect blood from patients who have had a positive oral food challenge or have been diagnosed as having a food allergy based on a positive skin prick test or elevated levels of allergen specific-IgE antibodies and a convincing history. The biorepository will also include blood from individuals with no history of food allergies.
