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.


60 or less is considered acceptable.


40 or less is acceptable. Antimony accumulates with age and recent evidence associates it with atherosclerosis and cardiovascular disease.

5 or less is acceptable.


Up to 0.8 is acceptable.


Up to 30 is acceptable.


Up to 4 is considered acceptable.

Mercury is not desirable in any amount but the healthy human body has always contained a baseline amount of mercury


Up to 5 is considered acceptable.


From 65 to 300 is desirable. Selenium is an essential nutrient. Selenium is toxic only at extremely high levels.


Acceptable up to 60.
