Hi Sean, if you are looking to get a diagnosis on mercury poisoning it might be worth getting a urine polyporhin test

as it can be a marker for poisoning. I am asking my GP about this aswell.

I am in N. Ireland btw, where did you go to get your amalgams replaced? There is only 1 or 2 biological dentists in the north AFAIK.
