Determination of aluminum concentrations in biological specimens: application in the clinical laboratory [PDF]
Advances in Laboratory Medicine, 2022 Aluminum enters the body primarily through diet or occupational exposure, and is cleared through urine. However, this trace element may accumulate and cause toxicity in subjects with renal insufficiency, and even in dialysis patients.
