I think you are right about the EDT test. I think it shows when things aren't functioning properly, but must not be able to detect mercury as the cause (even though I know of one person that was in the office at the time I was and she said her test showed up mercury-maybe it was still in her blood??) Anyway, I think that it may be like having your blood serum levels checked and the Dr. says that everything is "great" when you can still have total body deficiencies of things such as magnesium that serum levels can't show.

I think that I will write to my naturopath and tell them what I have found and at least let them be aware of that possibility so that maybe others want be misled.
