To determine our exposure and tissue levels of toxic metals hair and/or blood and/or urine may be tested. Each sample (hair, blood, or urine) offers a unique vantage point for assessing element status in the body. Hair tissue mineral analysis provides a convenient and accurate measure of both long and short-term toxic exposure and nutrient deficiencies. The test includes measures of pervasive and potentially damaging toxins such as lead, mercury and cadmium, along with crucial mineral nutrients like zinc, calcium, and magnesium. Test reports come with a unique index that clearly displays the likelihood of external contamination for each element, placing results into their proper perspective and ensuring the highest degree of accuracy. The hair tissue mineral analysis results may indicate a need for further investigation or treatment. For example, a urine challenge will help to confirm a heavy metal toxicity problem and guide Chelation Therapy treatments.
