Special Info
Patient Prep: High concentrations of iodine may interfere with testing. Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, non-essential over-the-counter medications (upon the advice of their physician). Avoid iodinated or gadolinium-based contrast media for at least 72 hours or 14 days for patients with impaired kidney function. Collection: Collect in a plastic container, mix well and aliquot into a trace metal free transport tube (ARUP #43116). Record total volume and collection time interval on specimen. Urine transported in a non-trace element-free tube or contaminated with iodine, gadolinium, blood, fecal material or acid preservative will be rejected. 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.
