There is one more test you need to take that is rare and hard to find a practitioner who knows how to do it. That is, the Carroll food intolerance Test which is only done by a handful of naturopaths. This tests for digestive enzyme deficiency intolerances, and is the only one that does so. All other tests are immune-mediated allergy/intolerance tests and look for a different class of food problems. The one I mention here doesn't elicit immune system symptoms, but it is an underlying problem from which many allergies arise, systemic, incurable, and often of serious consequence when people have otherwise no clue as to the cause of disease. My old doc, Harold Dick, ND cured many MS patients with a permanent change of diet based on the test which diagnoses food combination intolerances also, something no other test can do, and mineral salt deficiencies, which are important also. Along with the diet restrictions and Constitutional Hydrotherapy, the man performed "miracles" although he just had an understanding of Science and nature and how to use them. He is long gone, but daughter Dr. Letitia Watrous, ND carried on his work, based on the findings of naturopathic giant, pioneer Dr. O.G. Carroll.
