Which first - Chelation or Iodine? Or both?

Hello all I have been parasite cleansing, zapping, liver flushing, bowl cleansing, etc. and trying to plan out my next steps. My Analytic Research Labs hair analysis shows high mercury, copper, and aluminum andl low trace minerals despite a very clean organic diet. I have yet to do an Iodine loading test but I am pretty sure that it is quite low. So once I do the Iodine test and assuming that a need iodine, where should I start? Chelation or iodine? I figured both at the same time would be too much detoxing at once but maybe they go together well? Any advice is appreciated. Thanks-Justin
