Urine aluminum may be useful for monitoring aluminum exposure and is preferred in the assessment of chronic exposure. For aluminum toxicity due to dialysis or for routine screening, Aluminum, Serum (0099266) is preferred.
- Patient Preparation
- Diet, medication, and nutritional supplements may introduce interfering substances. Patients 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. Abstinence from iodine-containing medications or contrast agents for at least 1 month prior to collecting specimens for elemental testing is recommended.
- 24-hour or random urine collection. Specimen must be collected in a plastic container. ARUP studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately, if tested within 14 days of collection.
- Specimen Preparation
- Transfer an 8 mL aliquot from a well-mixed collection to ARUP Trace Element-Free Transport Tubes (ARUP supply #43116). Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. (Min: 1 mL)
- Storage/Transport Temperature
- Refrigerated. Also acceptable: Room temperature or frozen.
- Unacceptable Conditions
- Urine collected within 48 hours after administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies). Acid preserved urine. Specimens contaminated with blood or fecal material. Specimens transported in non-trace element-free transport tube (with the exception of the original device).
- Record total volume and collection time interval on transport tube and on test request form.
- Ambient: 1 week; Refrigerated: 2 weeks; Frozen: 1 year
