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.
Total iron-binding capacity increases when iron deficiency exists. [4] 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]
The most reliable method to determine if you have an iron deficiency is to get a blood test, such as a serum ferritin test, which measures the amount of stored iron in your body, as well as a ...
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]
Low ferritin may also indicate hypothyroidism, [37] vitamin C deficiency or celiac disease. [citation needed] Low serum ferritin levels are seen in some patients with restless legs syndrome, not necessarily related to anemia, but perhaps due to low iron stores short of anemia. [38] [39]
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 ...
This mighty mineral courses through our veins, quite literally, playing a pivotal role in transporting oxygen and keeping our energy levels from dipping lower than our mid-day motivation at work ...
But, if you have low iron levels, you're not into supplements, and your doctor gives the OK, experts say you’re probably fine to go the fish route. “But if you find yourself nauseous ...
