The ferritin levels measured usually have a direct correlation with the total amount of iron stored in the body. However, ferritin levels may be artificially high in cases of anemia of chronic disease, where ferritin is elevated in its capacity as an inflammatory acute phase protein and not as a marker for iron overload. [citation needed]
With ferritin levels higher than 100 ng/mL, an increase in infections has been reported. [12] Another way to treat LID is with an iron-rich diet with ascorbic acid or vitamin C , contained in many types of fruits such as oranges , kiwifruits , etc., which will increase iron absorption 2- to 5-fold.
Iron-deficiency anemia is confirmed by tests that include serum ferritin, serum iron level, serum transferrin, and total iron binding capacity. [59] A low serum ferritin is most commonly found. However, serum ferritin can be elevated by any type of chronic inflammation and thus is not consistently decreased in iron-deficiency anemia. [23]
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. [7] [32] [33] In males and postmenopausal females, normal range of serum ferritin is between 12 and 300 ng/mL (670 pmol/L) .
Iron tests are groups of clinical chemistry laboratory blood tests that are used to evaluate body iron stores or the iron level in blood serum. Other terms used for the same tests are iron panel , iron profile , iron indices , iron status or iron studies .
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]
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
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.
