A member asked:

Why would my ferritin be low 5.5 but my iron levels are normal?

A doctor has provided 1 answer

Stores vs. current: Ferritin represents stores, serum iron reflects the short term status. An analogy - A propane tank will give a normal pressure reading when almost empty (serum iron) if you weigh the tank (Ferritin) you will know that it is almost empty.
