For Ferritin 30 -100, sugest adding on CRP, as Ferritin rises in acute and chronic inflammatory reactions, and may be falsely normal. If Ferritin >100, then iron deficiency is unlikely, regardless of inflammatory state.

Ferritin is an unreliable indicator of iron stores for 4-5 weeks after an iron infusion.

Serum Ferritin does not always reflect the state of body iron stores.

In a number of conditions ferritin levels may be elevated independently of the patient's iron stores and confuse interpretations.

It is also present in hepatocytes and may be elevated in hepatocellular damage. An assessment of iron deficiency or overload using serum ferritin is difficult in these circumstances.

Laboratory Use Only
Storage Instructions:


Most patients have a low serum iron for a few weeks after major surgery, even though ferritin is frequently raised. Assessment of iron stores should occur after convalescence.
