Collection Requirements

Patient Preparation: Patients should be encouraged to discontinue vitamins, nutritional supplements, and nonessential over-the-counter medications prior to specimen collection, and avoid shellfish and seafood for 48-72 hours. High concentrations of iodine may interfere with elemental testing. Abstenence from iodine-container medications or contrast agents is recommended at least 1 month before sample collection. Collection of urine specimens from patients receiving iodinated or gadolinium based contrast media should be avoided for a minimum of 72 hours post-exposure. Collection from patients with impaired kidney function should be avoided for a minimum of 14 days post-contrast media exposure.
