Hmm-- I was going to order one to have my daughter do too, but the main thing I was wanting to check for, is uranium- because of having been in the military, exposed to depleted uranium. You're right, it's not included in the test I got for myself. Neither is antimony, beryllium, bismuth, platinum, thallium, uranium, silver tin, and titanium. sheesh.
I was mainly interested in the minerals, glands, nutritional stuff for myself. Now that I know better, I wouldn't do it again, but the ND had me do a DMSA urine test, which included most of those metals. Lead was extremely high.
Even having the 6 crowns in my mouth still, mercury didn't show as a problem, but that's not uncommon to not have mercury show in any kind of testing, with Lyme involved.
I think there's only two lab's that don't wash the hair, but I wonder if a person specifically asked for the hair to not be washed, if Doctor's Data would listen? It would be worth asking. For my daughter, more metals need to be tested too.
