Specimen Collection Requirements

Patient Preparation

Diet, medication and nutritional supplements may introduce interfering substances. Patient 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. Abstain from iodine containing medications or contrast agents for at least 1 month prior to collecting spceimen.
