How to read this marker

Calculated from iron and TIBC. Fasting and timing improve consistency.

The wider testing context

Iron tests tell a fuller story when read together. The time of the test, fasting, inflammation, liver health, and supplements may affect the numbers.

Using this range

These are starting ranges for adults who are not pregnant, unless this page says otherwise. Your lab may use a different range. Compare the units, sample, and collection details with your own report. Medicines and health history also matter. Ask your clinician what your result means for you.

A question to bring to your visit

How does the Transferrin saturation range here compare with my lab’s range, and what else matters for me?

Compare with your report

Before discussing a result, keep these details together:

  • Your result and its units
  • The range printed by your own lab
  • When the sample was collected, and the sample type or method if shown
  • Medicines, supplements, and changes in your health that may matter

A number on this page cannot diagnose a condition or choose a treatment for you. Your clinician can help put it in context.

Dr. Purser’s adult reference range may differ from the range printed by your lab. Compare the units and discuss your result with your clinician.
