[34] [35] [36] In premenopausal females, normal range of serum ferritin is between 12 and 150 [34] or 200 [35] ng/mL (330 or 440 pmol/L). [36] In those with hemochromatosis, the serum ferritin level correlates with the degree of iron overload. [7] Ferritin levels are usually monitored serially in those with hemochromatosis to assess response to ...
Serum ferritin is a low cost, readily available, and minimally invasive method for assessing body iron stores. However, the major problem with using it as an indicator of hemosiderosis is that it can be elevated in a range of other medical conditions unrelated to iron levels including infection, inflammation, fever, liver disease, renal disease ...
Proinflammatory states account for up to 90% of raised ferritin. [57] [58] [4] Serum ferritin in excess of 1000 ng/mL of blood is almost always attributable to haemochromatosis. [citation needed] Other blood tests routinely performed include blood count, renal function, liver enzymes, electrolytes, and glucose (and/or an oral glucose tolerance ...
Plasma levels for the iron-drug complex climax after one hour of intake and the drug has a half-life of 160 minutes. Most of the iron-drug complex is therefore excreted within three to four hours following administration, the excretion occurring mostly in urine (90%).
Ferritin genes are highly conserved between species. All vertebrate ferritin genes have three introns and four exons. [8] In human ferritin, introns are present between amino acid residues 14 and 15, 34 and 35, and 82 and 83; in addition, there are one to two hundred untranslated bases at either end of the combined exons.

Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [28] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [29] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [25]

Adult-onset Still's disease is rare and has been described all over the world. The number of new cases per year is estimated to be 1.6 per 1,000,000 population. [ 1 ] The number of people currently affected is estimated at 1.5 cases per 100,000–1,000,000 population. [ 21 ]
