Aside for a hair test, what is a accurate test for mercury? I understand that using a provoking agent is a bad ideas because it skews the results because the reference values are for people without DMPS or DMSA or EDTA etc. My doctor says he does both, with and without. Anybody have any experience with this? What does Huggins or Cutler say is accurate. My hair test shows high Nickel lower end calcium and the rest of the minerals are within limits.
