If ferritin is high, there is iron in excess or else there is an acute inflammatory reaction in which ferritin is mobilized without iron excess. For example, ferritins may be high in infection without signaling body iron overload. Ferritin is also used as a marker for iron overload disorders, such as hemochromatosis or hemosiderosis.
Examples include albumin, [9] transferrin, [9] transthyretin, [9] retinol-binding protein, antithrombin, transcortin. The decrease of such proteins may be used as markers of inflammation. The decrease of such proteins may be used as markers of inflammation.
Measuring ferritin provides a crude estimate of whole-body iron stores, though is raised in many conditions, particularly inflammatory conditions. Examples of causes for raised serum ferritin include but are not limited to: infection, chronic alcohol consumption (mainly >20g/day), liver disease, cancer, porphyria, Hemophagocytic ...
Serum ferritin testing is a low-cost, readily available, and minimally invasive method for assessing body iron stores. However ferritin levels may be elevated due to a variety of other causes including obesity, infection, inflammation (as an acute phase protein), chronic alcohol intake, liver disease, kidney disease, and cancer.
Serum iron is a medical laboratory test that measures the amount of circulating iron that is bound to transferrin and freely circulate in the blood. Clinicians order this laboratory test when they are concerned about iron deficiency, which can cause anemia and other problems. 65% of the iron in the body is bound up in hemoglobin molecules in red blood cells.
Inflammatory cytokines stimulate the liver to produce the iron metabolism regulator protein hepcidin, that reduces available iron. If hepcidin levels increase because of non-bacterial sources of inflammation, like viral infection, cancer, auto-immune diseases or other chronic diseases, then the anemia of chronic disease may result. In this case ...
Tests for rheumatoid factor and anti-nuclear antibodies are usually negative and serum ferritin is markedly elevated. Patients experiencing a flare-up from adult-onset Still's disease usually report extreme fatigue, swelling of the lymph nodes and, less commonly, fluid accumulation in the lungs and heart.
Hemosiderin or haemosiderin is an iron-storage complex that is composed of partially digested ferritin and lysosomes. The breakdown of heme gives rise to biliverdin and iron. [1] [2] The body then traps the released iron and stores it as hemosiderin in tissues. [3] Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. [3]
