Specimen:
Urine More information
Minimum:
Preferred Minimum: 8 mL aliquot from a well-mixed collection
Absolute Minimum: 1 mL aliquot from a well-mixed collection
24 hr or random urine collection in a plastic bottle; refrigerate during collection.
Absolute Minimum: 1 mL aliquot from a well-mixed collection
24 hr or random urine collection in a plastic bottle; refrigerate during collection.
Rejection Criteria:
Urine collected within 48 hours after administration of a gadolinium
(Gd) containing contrast media (may occur with MRI studies). Acid
preserved urine.
Specimen
Instructions:
High concentrations of iodine may interfere with elemental testing.
Abstinence from iodine-containing medications or contrast agents for at
least 1 month prior to collecting specimens for elemental testing is
recommended.
Specimen must be collected in a plastic container and should be refrigerated during collection. Studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately, if tested within 14 days of collection.

Interpretive Data:
Urine mercury concentration may correlate better with inorganic mercury
exposure than blood concentrations since organic mercury is eliminated
primarily in the feces. Urine mercury levels may also be used to
monitor chelation therapy.
Comments:
Record total volume and collection time interval on transport tube and
on test request form.
Stability: Mercury is volatile; concentration may reduce after seven
days or more storage.
Methodology:
Inductively Coupled Plasma/Mass Spectrometry
CPT Code:
83825
