I've had a patch test done about 7 years ago now and I had mild sensitivities to 2-3 chemicals but nothing that I use on a daily basis. Thanks for the pointers on the others. I'm hoping that any allergies will crop up via tests carried out through the naturopath, they are pretty extensive tests. One is a full nutritional evaluation and the other is a comprehensive GI effects profile (stool test). I'm open to any/all diagnostic testing right now.
