Apparently, the bad reviews were from people who can't read. The results I received backed up my true-life experiences and filled in a couple of gaps. I've had extreme digestive issues for well over 20 years. The usual skin prick allergy tests were dead ends and extremely frustrating, as I was still having intolerable symptoms. Only intolerance testing has been successful in pointing out my problem foods. I'm very happy with the results of this test. It was thorough. And, as the related tests have pointed out, I'm also too high in mercury and some other metals. I would never have known that and been able to take care of it without this test leading me into the knowledge. If you know the difference between allergy and intolerance, TAKE THE TEST.
