Fecal Metal Test - An excellent test for heavy and toxic metals along with the Toxic Element Clearance Test.
Analysis of elements in feces provides a comprehensive evaluation of environmental exposure and accumulation.
For several toxic elements such as mercury, cadmium, lead, antimony and uranium, biliary excretion of metals into feces is the primary natural route of elimination from the body.
Analysis of elements in feces provides important information about the potential for toxic metal burden. For many toxic metals, fecal (biliary) excretion is the primary natural route of elimination
from the body. Fecal elemental analysis also provides a direct indication of dietary exposure to toxic metals. Specimen collection is convenient for the patient and only requires a single-step
procedure.
Analysis of elements in feces provides a comprehensive evaluation of environmental exposure, potential for accumulation in the body, 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.
Evidence for the extent of exposure to mercury from dental amalgams is provided by the fact that fecal mercury levels are highly correlated with the number of amalgams in the mouth. It also clear
that fecal mercury levels for people with dental amalgams are remarkably similar from day to day, and approximately ten times higher than in people who do not have mercury amalgams.
Administration of pharmaceutical metal binding agents results in excretion of toxic metals primarily through the kidneys into the urine. In contrast, support of natural detoxification processes
enhances the rate of excretion of toxic metals into the feces. Elemental analysis of fecal specimens can provide a valuable tool to monitor the efficacy of natural detoxification of metals in infants
or patients who are on very limited and defined diets that do not contain contaminated solid foods. A preliminary study performed at Doctor’s Data indicates that biliary/fecal excretion of
mercury and lead may be markedly enhanced following high dose intravenous administration of ascorbic acid. Other orthomolecular or nutraceutical protocols may also enhance the fecal excretion of
metals and hence potentially decrease burden on the kidneys.
The fecal metals test was not developed to replace the pre and post urinary toxic metals provocation test, but rather provides an alternative for infants, children or adults for whom urine collection
is problematic, or for individuals who do not tolerate the available pharmaceutical metal detoxification agents. Elements are measured by ICP-MS and expressed on a dry weight basis to eliminate
variability related to water content of the specimen.
