Notes: 

Clinical Indications: May be useful in the assessment of acute or chronic elemental or inorganic mercury exposure and/or in monitoring chelation therapy. For the assessment of acute exposure, Mercury, Whole Blood (0099305) is preferred.

Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential 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.
