Interpretation of toxic metals in urine test
  • Applies to the "Toxic Metals in Urine Test" performed with Urine collected for 6 hours following a challenge chelation with a single 100/500 mg dose of DMSA by mouth.
  • All units are in micrograms of metal per gram of urine creatinine.
  • Interpretations below are those of M. Mirchandani, M.D. with research data available from various sources
  • Except for mercury and arsenic, most toxic metals are removed from the body by intravenous EDTA chelation therapy. Mercury removal requires DMSA by mouth.

Aluminum
