Reference Values
ARSENIC
0-35 mcg/L
Reference values apply to all ages.
LEAD
0-4 mcg/L
Reference values apply to all ages.
CADMIUM
0-15 years: not established
≥16 years: 0.0-1.3 mcg/L
MERCURY
0-15 years: not established
≥16 years: 0-9 mcg/L
Toxic concentration: >50 mcg/L
The concentration at which toxicity is expressed is widely variable between patients. 50 mcg/L is the lowest concentration at which toxicity is usually apparent.
Cautions
High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
