Hair analysis is used as forensic evidence by virtually every court room in the USA. Unlike blood testing hair analysis is not affected by what one eats,  it measures intracellular mineral absorption (inside the cell) whereas blood testing (aside from sodium and potassium) measures extra-cellular mineral absorption (outside the cell) and blood testing is affected by homeostatic mechanisms which can aften maintain normal mineral and toxis metal levels inspite of underlying toxicities and / or deficiencies. Hair testing is an accurrate record which can measure mineral absorption dating as far back as 4 - 5 months.
