ferritin

 [fer´ĭ-tin]
the complex of iron and apoferritin, a major form in which iron is stored in the body.

fer·ri·tin

(fer'i-tin),
An iron-protein complex, containing up to 23% iron, formed by the union of ferric ions with apoferritin; it is found in the intestinal mucosa, spleen, bone marrow, reticulocytes, and liver, and regulates iron storage and transport from the intestinal lumen to plasma.
See also: apoferritin.

ferritin

(fĕr′ĭ-tĭn)
n.
An iron-containing protein complex, found principally in the intestinal mucosa, spleen, and liver, that functions as the primary form of iron storage in the body.

ferritin

The principal IRON-binding protein of the body. Ferritin acts as an iron store in the liver and other tissues. Each ferritin molecule can hold up to 4500 iron atoms and the amount of iron in ferritin molecules accurately reflects the total iron stores of the body. Ferritin also protects against the toxic effects of excess iron.

ferritin

a conjugated, electron-dense protein concerned in the absorption of iron through the intestinal mucosa. It serves as a storage protein for iron in the liver and spleen.

Ferritin

A protein found in the liver, spleen, and bone marrow that stores iron.

Patient discussion about ferritin

Q. My Iron/TIBC tests normal, Ferritin,Serum = 22. Range 22-322. What is the problem? Iron Bind. Cap. ug/dL 324 range 250 - 450 UIBC ug/dL 206 range 150 - 375 Iron, Serum ug/dL 118 range 40 - 155 Iron Saturation % 36 range 15 - 55 Biopsy = Prostate Cancer....PCA high = 10.2 PSA now 8.3 PSA Ultra W/Serial Monitor ...Ultrasenitive = 8.26

A. What makes you think something is not normal? Ferritin values may be low in some people, and iron deficiency is usually defined as ferritin 15. Do you have anemia? Currently, it doesn't seem you have any problem with the iron levels.

Take care,
