Immunology of delayed food allergy.

ABSTRACT

Studies here and abroad are stockpiling evidence that immunoglobulin E explains only a small part of food allergy. Involvement of the entire immune system is evident if the more prevalent delayed-type food allergy is to be explained. To adequately diagnose food hypersensitivity a testing technique must be used that identifies delayed food allergy, such as the patch test here described, along with a test that diagnoses immediate immunoglobulin E-mediated food allergy.
