Serum Iron - Normal Values

Normal Values

Normal reference ranges are:

• Serum Iron (SI):
  • Men: 65 to 176 μg/dL
  • Women: 50 to 170 μg/dL
  • Newborns: 100 to 250 μg/dL
  • Children: 50 to 120 μg/dL
• TIBC: 240–450 μg/dL
• Transferrin saturation: 20–50%

μg/dL = micrograms per deciliter.

Laboratories often use different units and "normal" may vary by population and the lab techniques used; look at the individual laboratory reference values to interpret a specific test (for instance, your own).
