Methodology: Inductively Coupled Plasma/Mass Spectrometry (ICP/MS)
Edit Date: 8/6/2009
Performed: Wednesday, Saturday
Released: 1-5 days after setup at PeaceHealth Laboratories’ reference lab.
CPT Code: 82108-90
Specimen Collection Details
Collection: 24-hour urine in a clean plastic urine container. Also acceptable: Random urine. Refrigerate during collection, storage, and transport.
Handling: Mix well and record total volume. Aliquot into two ARUP Trace Element-Free transport tubes, available from PeaceHealth Laboratories Client Services.
Stability: 7 days ambient, 14 days refrigerated, or 1 year frozen. Studies indicate refrigeration of urine during and after collection alone preserves specimen adequately, if tested within 14 days of collection.
Standard Volume: 10 mL urine aliquot.
Minimum Volume: 5 mL urine aliquot.
Transport: Refrigerated.
Rejection Criteria: Urine collected within 48 hours after administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies); acid preserved urine.

Aluminum per gram of creatinine No reference interval (µg/g crt)
Urine aluminum values do not correlate well with exposure. Elevated levels should be confirmed with a second specimen due to a high susceptibility of the specimen to collection-related environmental contamination.
