ABSTRACT
A variety of unproven procedures to diagnose allergic and immunological diseases and speci c allergic sensitivities are currently marketed to both physicians and the general public. Some of them are based on false premises about disease pathogenesis, others on empirical and anecdotal experiences that have not been
diagnosis of disease based on these tests leads to inappropriate therapies, including unnecessary restrictions of diet and environmental exposures as well as the use of ineffective medications. Furthermore, a patient who wrongly believes that he or she suffers from allergy or an inadequate immune system because of a faulty test risks unnecessary restrictions and fears.
