Urine Mercury, ARUP #25050, EPIC: LAB6098, SOFT: XHGU
- A Urine Creatinine test is performed on each sample.
- Please refer to the Specimen Collection Manual for instructions on 24 Hour Urine Collection:
- Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, non-essential over-the-counter medications (upon the advice of their physician), and avoid shellfish and seafood for 48 to 72 hours.
- 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.
- Urine collected within 48 hours after administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies) will not be tested.

Quantitative Inductively Coupled Plasma/Mass Spectrometry.
Urine mercury levels for healthy subjects (reference population) are influenced by diet and environmental background exposure. Urine mercury levels up to 50 mcg/L can result from seafood diets, primarily methylmercury, without any clinical evidence of toxicity.
This assay monitors mercury exposure (primarily inorganic mercury).
