Hi Ann! Thanks for that link. Are they better than Great Smokies Labs? Beucase they have some tests I want to order and they also have the Hair analysis as well. I sure would hate to confuse my poor chiro. He's such a nice older gentleman and so kind of him to agree to order these things for me. Also, can you advise any other testing? Feel free to email me if you like ;-). I hope you're doing well. Are you rid of your excess Mercury now?
