Aluminum, 24‑Hour Urine without Creatinine
Use
Determines total aluminum excreted in a 24‑hour urine collection, useful for monitoring aluminum exposure in settings such as dialysis patients or those with occupational/environmental exposure; evaluation of prosthetic implant wear; cannot be substituted with serum aluminum measurements. Clinical interpretation should consider renal function and context. (Source: Mayo Clinic Laboratory description)

Limitations
Falsely elevated results may occur if non‑acid‑washed or metal‑cap containers are used. Preanalytical contamination is a major source of error in trace metals assays. Results should always be interpreted in clinical context. (Source: Mayo Clinic limitations and cautions)
