Dear Snowbird I went to a private hospital and had this done. They take a sample of your urine before and then put you on EDTA IV. This will pick up about ten different metals. The day after you have to have a vitamin drip to replace everything the EDTA removes. I would definitely recommend it. It does work. I don't know where you come from, but this is something I could not get done on the NHS, so had to pay, but it does work. I felt fine after, went out for dinner and felt fine. Are you from England, do you know where you can get it done? LOVE TRACY X
