This article explains what ferritin is, how it differs from iron and the symptoms iron deficiency and low and high ferritin levels.
What is ferritin?
Ferritin is not iron but is a protein in the body which contains iron.
As ferritin is the main form in which iron is stored in the body the amount of ferritin which is found in the blood reflects the amount of total iron which is available to your body.
Ferritin releases this iron as the body requires it for things like the production of new red blood cells.
Best Indicator Of Iron Deficiency
Ferritin is therefore the best indicator of iron deficiency. By assessing the levels of ferritin in the body, you can clearly identify whether you might be iron deficient or even have levels that are raised.
If a ferritin test comes back showing a risk of iron deficiency, further tests may be suggested by a medical professional, including a test for iron itself.
You can track your Ferritin level through a simple at home finger prick blood test.
