The document describes Quicksilver Scientific's Mercury Tri-Test, which analyzes mercury speciation and compartment ratios to assess mercury body burden and excretion without provocation. It separates methylmercury and inorganic mercury to reveal sources like fish or dental amalgams. Comparisons of mercury levels in blood, hair, and urine provide indices of each form's excretion ability. This helps identify issues like poor excretion or a methylmercury detox enzyme deficiency. The test aims to clearly show mercury status without using potentially harmful chelation agents like challenge tests.
