Fecal elemental analysis provides a direct indication of dietary exposure to toxic metals and indirect information about the potential for toxic metal burden. Chronic, low-level assimilation of toxic metals can result in accumulation in the body. For many toxic metals, fecal (biliary) excretion is the primary natural route of elimination from the body. Specimen collection is convenient for the patient and only requires a single-step procedure. Elements are measured by ICP-MS and expressed on a dry weight basis to eliminate variability related to water content of the specimen. 
Useful for:
