Storage Instructions:

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.

Ferritin is an acute phase reactant and may be elevated in acute and chronic inflammatory states.

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.

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.
