Aluminum, urine; creatinine, urine; aluminum:creatinine ratio; aluminum, urine (24-hour)
Do not use preservative. Preservatives used for routine analysis may contain mercuric oxide (ie, Stabilur), which interferes with all metal testing. If both urinalysis and metal testing are ordered, please submit a separate urine specimen (containing no additive) for the metal testing.
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Urine (random or 24-hour)
Plastic urine container, no preservative
Optional protocol: Instruct the patient to void at 8 AM and discard the specimen. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Avoid contact with metal during collection. Screw the lid on securely.
Maintain specimen at room temperature.
Monitor patients for prior and ongoing exposure to aluminum. Patients at risk include:
• Infants on parenteral fluids, particularly parenteral nutrition
• Burn patients through administration of intravenous albumin, particularly with coexisting renal failure
• Adult and pediatric patients with chronic renal failure who accumulate aluminum readily from medications and dialysate
• Adult parenteral nutrition patients (less so, recently)
• Patients with industrial exposure
Monitor dialysate and water to prepare dialysate to prevent aluminum toxicity in dialysis patients.
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Inductively coupled plasma/mass spectrometry (ICP/MS)
• Environmental exposure: 5−30 μg/L, 0−32 μg/24 hours
• Aluminum:creatinine ratio: <50 μg/g creatinine
• Occupational exposure: 150 μg/g creatinine (collected at end of shift)1
