I'm no doctor, but isn't ferritin the storage form of iron? If so (and I'm not sure of this) but then it may mean that you're using the iron (or something is using it). That's just a guess.
Are you getting any other mineral co-factors? I think copper, zinc, and esp molybdenum are involved in iron metabolism and storage, not to mention b12, folate, etc.
Here's a study that mentions the moly-b and ferritin connection:
