Special Info

Collection volume MUST be indicated. Diet, medication and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals and nonessential over-the-counter medications (upon the advice of their physician). High concentrations of iodine may interfere with elemental testing. Collection of urine specimens from patients receiving iodinated or gadolinium (Gd)-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. ARUP studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately, if tested within 14 days of collection. Urine collected within 72 hours after administration of iodinated or gadolinium (Gd)-based contrast media and acid preserved samples are unacceptable. Specimens contaminated with blood or fecal material and specimens transported in a non-trace element free transport tube (with the exception of the original device) are also unacceptable. This test is New York DOH approved.

Clinical Info

This assay provides limited utility in determining manganese exposure. Whole blood measurements are recommended for determining recent or active exposure.
