Serum iron, total iron-binding capacity (TIBC), and/or transferrin tests are usually ordered together and, subsequently, the transferrin saturation can be determined and used to assess how much iron is being carried in the blood. A ferritin test may also be used to evaluate a person’s current iron stores.

Serum iron levels are often evaluated in conjunction with other iron tests. A summary of the changes in iron tests seen in various diseases of iron status is shown in the table below.

Hemochromatosis High Low Low High High
Chronic Illness Low Low Low/Normal Low Normal/High
