Standard allergy testing relies on identifying the immunoglobulin (Ig) E antibody specific for the allergen in question. Two classic methods of doing this are the immediate wheal-and-flare skin prick tests (in which a small amount of antigen is introduced into the skin and the site is evaluated after 15 minutes for the presence of an immediate wheal-and-flare reaction) and in vitro (blood) testing. Methods of allergy testing that do not have a clear scientific basis include cytotoxic testing, provocation-neutralization testing or treatment, and “yeast allergy” testing.
