Serum iron is not a routine test. Low iron values in conjunction with elevated tibc values or speciically measured transferrin concentrations yielding less than 16 percent transferrin saturation generally indicate iron deiciency anemia world health organization 2001. Such tests include complete blood count or hemoglobin test.

It s usually ordered as a follow up when a more common test reveals abnormal results. Clinicians order this laboratory test when they are concerned about iron deficiency which can cause anemia and other problems.

Transferrin saturation values in excess of 60 percent may be indicative of hemochromatosis or iron overload. It is the value of serum iron divided by the total iron binding capacity of the available transferrin the main protein that binds iron in the blood this value tells a clinician how much serum iron is bound for instance a value of 15 means that 15 of iron binding sites of transferrin are being occupied by. Iron is a mineral in your body that comes from foods like red meat and fortified cereals or from supplements you take.
