Fecal analysis provides a direct indication of dietary exposure to toxic metals and indirect information about the potential for toxic metal burden. Also provides a comprehensive evaluation of environmental exposure, potential for accumulation in the body (Hg), and possibly endogenous detoxification of potentially toxic metals. For many toxic elements such as mercury, cadmium, lead, antimony and uranium, biliary excretion into the feces is the primary natural route of elimination from the body. The primary process by which the body eliminates the insidious sulfhydryl reactive metals is through the formation of metal-glutathione complexes, of which greater than 90% are excreted into the bile.
