What this test measures
Aluminium testing measures the total serum aluminium concentration by ICP-MS. Aluminium is the most abundant metal in the earth's crust and is ubiquitous in food, water, cookware and consumer products — but very little is absorbed orally in healthy people. The body excretes aluminium via the kidneys, so kidney failure dramatically raises aluminium retention.
Clinically relevant testing is mostly in: (1) chronic dialysis patients — historically aluminium-based phosphate binders and aluminium-contaminated dialysate caused dialysis encephalopathy and adynamic bone disease; modern dialysis avoids aluminium but accidental exposure still occurs; (2) workers in aluminium smelting, welding, grinding, and bauxite refining; (3) patients on long-term aluminium-containing antacids with kidney disease.
Why it matters
India's aluminium industry is large (NALCO, Vedanta, Hindalco) — smelting, refining, foundry, and grinding/finishing all generate aluminium dust and fumes that can be inhaled. Aluminium-induced occupational lung disease (aluminosis), encephalopathy, and neurological effects have been described. Occupational health surveillance in these industries requires periodic biological monitoring.
In dialysis units, aluminium testing remains important to avoid the now-rare but devastating syndrome of dialysis aluminium toxicity (encephalopathy, microcytic anemia not responsive to iron, bone disease). KDIGO guidelines recommend periodic monitoring in patients on long-term dialysis and avoiding aluminium-containing phosphate binders. Routine aluminium testing in asymptomatic, non-dialysis individuals is not evidence-based — claims linking aluminium intake to Alzheimer disease, autism or other conditions are not supported by the weight of current scientific evidence.
How to prepare
Use trace-element-free royal blue-top tubes (ordinary tubes have aluminium contamination). Stop aluminium-containing antacids for 48 hours before testing if possible. Tell the lab if you are on dialysis (sampled before a dialysis session). For occupational testing, sample at end of shift / end of workweek per ACOEM protocols.
Markers & reference ranges
Reference ranges below are typical adult values. Your lab's reported range may differ slightly based on the assay platform and patient demographics — always read your report against the range printed on it.
| Marker | Normal range | If low | If high |
|---|---|---|---|
| Aluminium (µg/L)[1][2][3] | General population: < 7 µg/L · Dialysis: < 20 µg/L target (KDIGO) | Normal background. | >20 µg/L in dialysis patients = retention; >60 µg/L = potential toxicity, consider DFO (desferrioxamine) chelation. In workers, >12 µg/L suggests significant occupational exposure — review controls. |
When to test aluminium
| Clinical situation | Test interval | Concern |
|---|---|---|
| Chronic hemodialysis | Annually + if symptoms | Encephalopathy, anemia, bone disease |
| Aluminium industry workers | Annual + post-incident | Aluminosis (lung), neurological |
| Long-term antacid use with CKD | Yearly | Accumulation |
| Asymptomatic healthy adult | Not recommended | No evidence basis |
Frequently asked questions
Does aluminium cause Alzheimer disease?
Despite older hypotheses, current evidence does not establish aluminium as a cause of Alzheimer disease. Major neurological societies do not recommend population-level aluminium avoidance to prevent dementia.
Should I avoid aluminium cookware?
Routine use of aluminium cookware has not been shown to raise body burden meaningfully in healthy adults. Anodised aluminium and non-stick coatings further reduce migration into food.
Should I check aluminium because I use aluminium foil and antiperspirant?
No — there is no evidence-based reason to screen healthy individuals for these reasons.
Why is the trace-element-free tube needed?
Ordinary rubber stoppers and standard tubes contain aluminium contaminants that can artificially raise results. Royal blue-top trace-element tubes are required.
How long does the report take?
Typically 3–5 days.
I am on dialysis — how often should aluminium be tested?
Annually in patients on long-term dialysis, or sooner if symptoms appear or exposure is suspected (KDIGO).
