What is the reference range for Urinary Mercury?

The standard reference range for Urinary Mercury is Typically <5 µg/g creatinine in populations without occupational or dental amalgam exposure.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

What does the Urinary Mercury test measure?

Q: What is Urinary Mercury?

Mercury exists in multiple forms — elemental, inorganic, and organic (methylmercury). Urinary excretion predominantly reflects inorganic and elemental exposure (dental amalgam, occupational vapour), whereas organic mercury from fish is largely excreted in faeces. Renal proximal-tubule transport actively secretes inorganic mercury into urine, making it a useful marker of recent exposure.

Q: Why is Urinary Mercury measured?

Elevated urinary mercury may indicate amalgam burden, occupational exposure, or recent chelation. It does not reliably reflect methylmercury body burden from dietary sources, which requires blood or hair analysis. Practitioners use urine mercury to screen patients with suspected inorganic exposure or to monitor post-amalgam-removal excretion.
