Clinical Indications

The main use for this test is in the investigation of iron overload, when the transferrin saturation should also be assessed.

Measurement of serum iron is of little relevance in the investigation of iron deficiency; levels fall during acute infection (e.g. a cold); in patients taking oral iron (or multivitamins) levels reflect recent intake and are not representative of the true physiological state
