My foot pad results!

Oh boy, I just got my results in the mail and I tested positive for everything except Nickel and Arsnenic! I am positive on Benzene, Isopropyl alcohol, copper, mercury, and PCB's! The mercury does not surprise me since I had my Amalgams removed during that time, but I have no clue as to the source of these other toxins. I will have to investigate. Guess I need to order more pads!! Dr. V, just how accurate are the test results? Is it possible to get a false negative or positive?
