Special Instructions
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration. It is important to use the correct collection tube and ensure immediate separation and transfer of specimens to certified metal-free tubes for shipment.
Limitations
Serum aluminum levels fluctuate with the use of aluminum-containing products and are quickly cleared by the kidneys if the renal function is normal. Elevated levels of aluminum can persist for over a week after beginning aluminum-containing antacid treatments. The test does not directly diagnose aluminum toxicity but indicates exposure levels, which must be interpreted in clinical context.
