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.
