Food allergy reactions cause various health disorders in sensitive people. These reactions may be IgE-mediated,cell-mediated, energy disturbance-mediated, or a combination of the three. Certain laboratory diagnostic procedures have been able to identify most IgE-mediated or cell-mediated food reactions, but so far there is no test available in traditional medicine to test the energy-mediated allergies and sensitivities. NAET® procedures have been able to identify food substances triggering to energ disturbances in sensitive people causing related health disorders. NAET uses one of the testing procedures called NST (Neuromuscular sensitivity testing).The efficacy of NST-NAET to screen food sensitivity will be evaluated in comparison with one of the well accepted, established, traditional medicine allergy testing known as the IgE-specific antigen test.
