Ferritin is a protein which stores iron and releases it when the body is in need of additional iron. Since serum ferritin levels offer a reflection of the body’s stored iron, it can therefore be used to assess how much stored iron the body has. Most of the body’s ferritin is located in:
- Liver tissues
- Spleen tissues
- Skeletal muscle tissues
- Bone marrow tissues
For maximal accuracy, combine this test with:
- Hemoglobin test
- Blood pressure checkup on both arms
- Blood glucose test
- Blood platelet count
- Red blood cell count
- White blood cell count
Indicator(s):
If ferritin levels are low, consider adrenal glands (mineral utilization factors), spleen, liver, and bone marrow.
If ferritin levels are high, inquire if the person is taking iron supplements.
