Why It’s Done
Doctors may order a ferritin test to:
• Diagnose iron deficiency anemia – Low ferritin levels can indicate low iron stores, often leading to anemia.
• Check for iron overload – High levels may suggest conditions like hemochromatosis or chronic inflammatory conditions.
• Monitor iron levels during treatment for iron-related disorders.
• Investigate unexplained fatigue, weakness, or chronic headaches, which can be symptoms of abnormal iron levels.
• Assess overall iron metabolism in chronic diseases like kidney disease or certain cancers.
Preparation
• Fasting: Usually not required, but your doctor might recommend fasting for 8–12 hours if other tests are being done simultaneously.
• Medications and supplements: Inform your doctor about any iron supplements, vitamins, or medications you’re taking, as they can affect test results.
• Timing: Schedule the test preferably in the morning, especially if other blood tests are ordered.
