CDC blasts improper hair and urine tests. The U.S. Centers for Disease Control and Prevention (CDC) has severely criticized the misuse of hair and urine tests to diagnose heavy metal toxicity. Last year, investigators from its National Institute for Occupational Safety and Health (NIOSH) evaluated a suspected outbreak of antimony toxicity among fire fighters in Boca Raton, Florida who had been wearing fire-retardant pants that contained various chemicals. The investigation was triggered by hair analysis and urine toxic metal tests that had been ordered by a chelationist (Leonard Haimes, M.D.) and performed by a commercial laboratory (Doctor's Data). Doctor's Data's reports alleged that all 30 of the fire fighters who had undergone hair analysis had antimony levels much higher than the "reference range" and that 23 who also had urine toxic metal testing showed "high" mercury levels. After a thorough evaluation found no real evidence of toxicity, the investigators advised:

The decision to perform laboratory testing for heavy metals, including antimony and mercury, should be based on whether or not documented health symptoms are consistent with overexposure to these metals. It is important to use reliable and recommended testing methods with well-validated reference ranges to measure the concentration of heavy metals in the body. Because results from elemental hair analysis and post-chelation-challenge urine tests do not provide sufficient evidence of heavy metal toxicity, they should not be used to justify searching the workplace for exposures or to treat heavy metal toxicity. In particular, they should not be used to justify chelation therapy, which can be potentially harmful to a patient. [dePerio MA, Durgam S. Evaluation of antimony and mercury exposure in firefighters.

After the CDC investigation was completed, most of the Boca Raton firefighters were reassured and withdrew their workers compensation claims. The rest of the claims were dismissed by the city, but the financial and/or emotional damage to the participants was considerable. At least 30 fire fighters spent about $500 each for their worthless evaluations by Dr. Haimes. The improper assessments caused widespread concern among the fire fighters, many of whom sought further medical evaluation elsewhere. Although most feel reassured, some have lingering doubts about what to believe. The City of Boca Raton, which is self-insured, spent money processing the worker's compensation claims, and the manufacturer of the fire-retardant pants lost sales of a perfectly good product.
