This is a questions regarding take-at-home heavy metal screening tests.
Basically, you put your pee in a test tube with "dithizone" and this little test square (catalyst or something, who knows) and dribble your urine in. You shake the tube and the upper part of the solution changes color according to the amount of free metal ions present in the urine.
an example of such a test. http://www.evenbetternow.com/Heavy-M...creen-Test.php
So, I bought one on sale, and the top of my solution was kind of greyish, supposedly meaning that I have a low concentration of heavy metals in my urine and/or a "mix" of metals (lead for instance would turn red if it was a big part of the solution)
Not that I'd interpret this as medical advice, as I plan to get my levels tested by a doctor, I'm just wondering if this test may be a parlor trick designed to convince everyone they're full of heavy metals (and that they should buy chelation supplements to counteract this) or if this may be a legit indicator tool.
Also, I don't think doing the test at home is that good of an idea, considering possible contamination/improper proceedure etc.
