Advances in the laboratory diagnosis of food allergy

Abstract

A great number of advances have been made in the diagnostic tools and testing methods available for foodallergy diagnosis. Improved and new methodologies have become available not only to identify the presence of a food allergy, but also to aid in determining the severity of an allergy, the likelihood of its resolution and potential cross-reactivity with other allergens. Cross-activity may include that between biologically related and unrelated foods or even between inhalant allergens. These testing methods may also improve patient outcomes by helping clinicians to provide accurate dietary advice and reduce the need for food challenges.
