Electroacupuncture according to Voll or EAV is a device used in alternative medicine. While some may use the device to diagnose ailments, for which there is no credible evidence of diagnostic capability, there are many that use the device for that of which is was designed, the measurement of energy on acupuncture end points.[1] The measurement of energy on acupunture end points was Dr. Voll's initial interest in EAV. It is registered with the FDA as a galvanic skin response measuring device. The American Cancer Society has concluded that the evidence does not support the use of EAV "as a method that can diagnose, cure, or otherwise help people with cancer."[2]

Units reportedly sell for around $15,000 and are promoted for diagnosis of conditions including "parasites, food and environmental sensitivities, candida, nutritional deficiencies and much more."[3] It is promoted for diagnosis of allergies but "results are not reproducible when subject to rigorous testing and do not correlate with clinical evidence of allergy".[1]

In tests, double-blind trials, "A wide variability of the measurements was found in most patients irrespective of their allergy status and of the substance tested. Allergic patients showed more negative skin electrical response at the second trial, compared to normal controls, independent of the tested substance. No significant difference in skin electrical response between allergens and negative controls could be detected."[4]
