Ferritin is a macromolecule with a molecular weight of at least 440
kD (depending on the iron content) and consists of a protein shell (apoferritin) of 24
subunits and an iron core containing an average of approx. 2500 Fe3+ ions (in liver and
spleen ferritin).1 In humans, it acts as a buffer against iron deficiency and iron overload.2
If the ferritin level is low, there is a risk for lack of iron,
which could lead to anemia or iron deficiency without anemia. In the setting of anemia, low serum
ferritin is the most specific lab finding for iron-deficiency anemia.3 Low ferritin may also
indicate hypothyroidism, vitamin C deficiency or celiac disease. Low serum ferritin levels
are seen in some patients with restless legs syndrome, not necessarily related to anemia, but
perhaps due to low iron stores short of anemia.4,5
A normal ferritin blood level, referred to as the reference
interval is determined by many testing laboratories. The ranges for ferritin can vary between
laboratories but typical ranges would be between 30–300 ng/mL (=μg/L) for males, and 30–160 ng/mL
(=μg/L) for females. A value less than 50 is considered as iron deficiency. Serum ferritin levels are measured in medical laboratories as part
of the iron studies workup for iron-deficiency anemia.6 The ferritin levels measured usually
have a direct correlation with the total amount of iron stored in the body.
