Biomarker Reference · Al
Aluminium (Blood) (Al) is a clinical biomarker used in heavy-metals-toxicology assessment. Aluminium is the most abundant metal in the Earth's crust and enters the body through diet, occupational inhalation, and medical sources such as dialysis and parenteral nutrition. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Aluminium is the most abundant metal in the Earth's crust and enters the body through diet, occupational inhalation, and medical sources such as dialysis and parenteral nutrition. It is neurotoxic and was historically associated with dialysis dementia and osteomalacia in renal-failure patients exposed to high-aluminium dialysate. Gastrointestinal absorption is normally very low except in renal impairment or with citrate co-administration.
Blood aluminium is ordered primarily in dialysis patients, where chronic elevation can cause dialysis encephalopathy, osteomalacia, and microcytic anaemia unresponsive to iron. It is also used to investigate occupational exposure in welders and smelters, or following high-dose antacid use in renal patients.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
2 tests on BiomarkersLabs.com include this biomarker.
Aluminium (Blood) reference range in this test: <10 µg/L (general population); <20 µg/L in patients on dialysis.
Aluminium (Blood) reference range in this test: Background population typically <10 µg/L; higher values may be seen with occupational exposure or contaminated dialysate.
