As many as 50 to 90 percent of food allergies are not allergies, according to a report released last week by the National Institute for Allergy and Infectious Diseases. The report issued new guidelines for diagnosing and treating food allergies, which are expected to result in fewer diagnoses and improved treatment.
The new guidelines emphasize the importance of combining a detailed medical history, a physical exam, skin-prick test and, in some cases, an oral food challenge in diagnosing food allergies. Blood tests are not reliable by themselves, and are often misinterpreted.
Dr. Rajeev Kishore, the director of the Akron Children’s Hospital Allergy and Immunology Center, gives his take on the new guidelines in this video.
