Lithium Heparin tube required. No need to separate.
Aluminium toxicity mainly arises in patients with chronic renal failure who are undergoing treatment either by conservative means or by maintenance haemo or peritoneal dialysis. Greatly elevated serum aluminium concentrations in these patients are clearly associated with the symptoms of dialysis encephalopathy (speech disorder, dementia, convulsions and death) and dialysis osteodystrophy (osteomalacia frequently resistant to treatment with vitamin D or its active metabolites). Aluminium accumulation may be responsible, in part at least, for the anaemia and soft tissue calcification of chronic renal failure. High concentrations may also be cardiotoxic.
The increased body burden comes from two sources.
The aluminium content of certain blood products and intravenous fluids may pose a considerable risk to individuals receiving them on a long term basis, particularly premature infants in whom renal function may be impaired.
Also, rare occupational exposure from working in factories and warehouses where aluminium is produced or welding takes place may increase exposure. Occupational exposure to dust containing finely divided aluminium may cause pulmonary fibrosis. It has been suggested that uptake of aluminium into brain may be responsible for the symptoms of Alzheimer’s disease.
Aluminium is a non-essential trace element with little known about its biological function. There has been no known cases of Aluminium deficiency and its measurement in this situation is not required.
Metal needles and cannulae must be flushed by drawing 2-3mL of blood into a syringe and discarding the sample. Use a new syringe for the sample that is to be used for aluminium analysis.
Requested in patients with chronic renal failure.
Water & Dialysis fluid can be measured.
<0.37 umol/L: Normal (no history of CRF).
<2.22 umol/L: Desirable in CRF patients.
>2.22 umol/L: Excessive accumulation.
>3.70 umol/L: Cause for concern, high risk of toxicity in children.
>7.41 umol/L: Urgent action required; High Risk of toxicity in all.
