Nutrient and Toxic Elements

Specimen: Hair

Price: £75.00

Since the body is unable to produce essential elements, those that are needed for function must be regularly consumed to make up for daily losses. Sometimes, however, exposure to elements that are needed in only very small amounts (or not at all) may be in excess and can cause toxicity. Measuring the trace element content of hair is a method of screening for possible health threats due to deficiencies or excesses of minerals. Hair reflects a longer interval of time than most tissues and body fluids.

Hair has a long history of successful use in detecting chronic exposure to toxic heavy metals in humans and animal models because hair concentrates heavy metals several hundred fold above concentrations found in blood. When any of the toxic heavy metals are elevated in hair, there is reason to investigate the origin of exposure. High levels in hair may reflect early chronic exposure before other signs and symptoms appear.
