Iron in ferritin or hemosiderin can be extracted for release by the RE cells, although hemosiderin is less readily available. Under steady-state conditions, the level of ferritin in the blood serum correlates with total body stores of iron; thus, the serum ferritin FR5Rl is the most convenient laboratory test to estimate iron stores.
These intestinal lining cells can then either store the iron as ferritin, which is accomplished by Fe 2+ binding to apoferritin (in which case the iron will leave the body when the cell dies and is sloughed off into feces), or the cell can release it into the body via the only known iron exporter in mammals, ferroportin.
This is in contrast to transfusional iron overload in which iron deposition occurs first in the reticuloendothelial cells and then in parenchymal cells. This explains why ferritin levels remain relative low in Hereditary hemochromatosis, while transferrin saturation is high. [23] [24]

Ferritin is an iron reservoir for an individual cell. It is found in all cells types and localized in the cytosol. Ferritin is a large protein composed of 24 subunits surrounding a core full of iron atoms. It is capable of holding 0-4500 iron atoms, [19] which can be used as a reservoir for cellular needs.
Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. [3] It is only found within cells (as opposed to circulating in blood) and appears to be a complex of ferritin, denatured ferritin and other material. [4] [5] The iron within deposits of hemosiderin is very poorly available to supply iron when needed.
