Intended Use
For the quantitative in vitro determination of Iron/UIBC in serum. This product is suitable for both manual and automated use.
Clinical Significance
The concentration of serum iron reflects principally the concentration of ferric iron bound to serum transferrin, a protein responsible for transporting iron from the intestine to the cells were it is needed.
Iron deficiency is one of the most prevalent human disorders. In adults iron deficiency is often symptomatic of chronic blood loss. Iron measurements are particularly beneficial when determining if anaemia is due to iron deficiency or long term illness. Serum iron concentrations also appear to be decreased in acute or chronic inflammatory disorders such as acute infection, immunisation or myocardial infarction.
Elevated levels of serum iron are present in haemochromatosis a genetic condition where too much iron is present in the body. Higher than normal levels of iron are also known to occur as a result of blood transfusion, hepatic disease, renal disease and lead poisoning.
Principle
In the measurement of serum iron, ferric iron is dissociated from its carrier protein, transferrin, in an acid medium and simultaneously reduced to the ferrous form. The ferrous iron is then complexed with the chromogen, a sensitive iron indicator, to produce a blue chromophore which absorbs at 595 nm.
In the measurement of unsaturated iron binding capacity (UIBC) a known amount of ferrous iron is added, in excess, to the serum at alkaline pH. This saturates the unoccupied iron binding sites on the transferrin. The amount of free iron thus measured is subtracted from the total amount added to calculate the UIBC.
