Specimen:    8 mL aliquot from a 24 hour or random urine collection. Patient Prep: Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, nonessential over-the-counter medications (upon the advice of their physician). 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 refrigerated during collection.

A 24-hour sample is preferred, but a random sample is also acceptable.
Minimum Spec:    1 mL
Transport Temp:    Refrigerated
Spec Stability:    Stable up to 2 weeks refrigerated.
Ref Lab/Code:    ARUP 0025050
  Method:    Inductively Coupled Plasma/ Mass Spectrometry
Note:    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.
Processing Info:    Send 8 mL of urine sample in ARUP's Trace Element-Free Transport Tubes (clear w/blue caps).

Record total volume and collection time interval on the transport tubes labels and on the packing list
