Toxic metal screening includes lead, mercury, cadmium, arsenic, nickel, and aluminum.  A very high reading may represent a toxic amount of the mineral in the hair, and/or in the body tissues in general. In the case of a toxic metal, any deposition or accumulation in the hair indicates some degree of toxicity.

High levels of toxic metals inhibit the body‟s ability to process and assimilate specific nutritional elements that are essential to good health and have a proven link to many types of diseases.
