I have had a hair mineral analysis. It was quite interesting to do and Andy Cutlers book interpretting hair analysis is good. As you probably know mercury wont necessarily show up in hair but Cutler says look for signs of deranged mineral transportation. Mercury affects this and this is what he has based his counting rules on.

My hair results came up okay though and i did not meet the counting rules even though i know i am toxic, so even this method is not necessarily conclusive.
