Abstract
The tools available for diagnosing food allergy include the clinical history, physical examination, trial elimination diets, diet diaries, skin prick testing (SPT), and allergen-specific serum immunoglobulin E (IgE) testing. Clinician-supervised oral food challenges remain the gold standard and are often required to confirm or rule out the diagnosis because of the limitations in the diagnostic accuracy of the other methods available.
Improved or new testing methodologies are needed for determining the presence and severity of a food allergy and the likelihood of resolution of an allergy. This topic reviews improvements in available diagnostic tools and new testing methods that are in development. Current diagnostic tools are discussed separately, as is the initial evaluation of a patient with suspected food allergy.
