Sandra,
Copper is indistinguishable from Mercury. A DDI hair test from directlabs.com and Cutlers book goes a long way. Mercury messes up mineral transport (ie derranged skewed minerals =counting rules.) Copper does not. Alot of people have both like myself. I get copper dumps when I take Vitamin C, for mercury people it should make them feel better. I believe alot of my symptoms 50-75 are copper and the other 25% are mercury. However, remember mercury is probably what is causing the copper retention other then outside genetic factors, like pyroluria.
