The correlation between the levels of excretion in the urine and the clinical symptoms is considered poor, but urinary mercury (Hg) is the most reliable way to assess exposure to inorganic mercury.
For additional information, see HG / Mercury, Blood.
Detecting mercury toxicity
Daily urine excretion >50 mcg/day indicates significant exposure (per World Health Organization standard).
To avoid contamination by dust, the specimen should be collected away from the site of suspected exposure.
High concentrations of gadolinium and iodine are known to interfere with most metals tests. If gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
0-15 years: not established
> or =16 years: 0-9 mcg/L
