This test is routinely performed on all requests for serum iron, subject to sufficient specimen being available.
Turnaround Time: Within 3 hours
Diagnostic Use and Interpretation
This is a better index of iron availability to tissues than serum iron alone.
Iron saturation is increased in haemochromatosis or iron overload from any cause, and in acute iron poisoning.
Iron saturation is decreased in iron deficiency, and in anaemia associated with chronic disorders (where there may be functional iron deficiency).
