Ferritin is a biomarker that reflects iron stores in the body. Testing ferritin levels on a blood panel is one of the diagnostic thresholds of diagnosing iron deficiency, says von Drygalski. The ...
Menstrual bleeding is a common cause of iron deficiency anemia in women of childbearing age. [28] Women with menorrhagia (heavy menstrual periods) are at risk of iron deficiency anemia because they are at higher than normal risk of losing more iron during menstruation than is replaced in their diet. Most women lose about 40 mL of blood per cycle.
Serum ferritin levels reflect the iron stores available in the body. [4] The normal range is 20 to 200 nanograms per milliliter (ng/mL) for men and 15 to 150 ng/mL for women. [8] Low levels (< 12 ng/mL) are specific for iron deficiency. [4] However, inflammatory and neoplastic disorders can cause ferritin levels to increase – this may be seen ...
For this reason, low ferritin levels carry more information than those in the normal range. A falsely low blood ferritin (equivalent to a false positive test) is very uncommon, [35] but can result from a hook effect of the measuring tools in extreme cases. [36] Low ferritin may also indicate hypothyroidism, [37] vitamin C deficiency or celiac ...
Figure shows normal red blood cells flowing freely in a blood vessel. The inset image shows a cross-section of a normal red blood cell with normal hemoglobin. [34] The causes of anemia may be classified as impaired red blood cell (RBC) production, increased RBC destruction (hemolytic anemia), blood loss and fluid overload (hypervolemia ...
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 ...
In fact, recent research estimates 40% of girls and young women aged 12 to 21 in the US are affected by iron deficiency, with menstruation listed as the primary risk factor. Pregnancy and ...
A blood smear showing hypochromic (and microcytic) anemia. Note the increased central pallor of the red blood cells. Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (Hypo- refers to less, and chromic means colour.) A normal red blood cell has a biconcave disk shape and will have an ...
