Good luck with everything, I hope the results of the heavy metal testing are good. I am getting a heavy metal test done as well, but I don't believe it included anything for copper. I will ask my Neuro about that. Was it a urine screen or a blood sample? As far as your experience with the Cleveland Clinic, I had a similar one as well. I was diagnosed with MG back in 2008 and the Cleveland Clinc is a place I went to that said I didn't have anything wrong with me. I think they're just like most doctors and most don't tend to think outside of the box. Good luck with everything
