this is off topic but you seem like the person to ask-
I purchase a home heavy metal screen test, the test is "based on the dithizone reaction method" where a piece of dithizone test paper is put into a solution (which turns green) and then urine is added. The test can detect seven different metals. My test showed no heavy metals.
Two questions-do you feel this test is accurate? Currently I am drinking a lot of beet and onion juice, do you think that this could reduce my heavy metals enough to cause the test to show up negative?
