I had a hair test done back in 2001 that read off of the charts. I also did a chelating challenge at that time that read off of the charts. I have a hair test kit here and was going to do it. But I just spent a lot of money on other tests (a 24 hour urine metals before NCD, a 24 hour urine metals after NCD will be done once I get up to the 30 drops per day), a whole bunch or hormone tests (thyroid, dhea, adrenals, estrogen, progesterone, you name it). I hope my insurance will cover all of these as they are from alternative labs. But I guess I should do the hair test too because that will give me a good baseline level to compare to later like you are doing. When you do the test, let me know if your levels are lowered.
