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.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
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 .
Normal reference ranges are: [citation needed] Serum iron: 60–170 μg/dL (10–30 μmol/L) Total iron-binding capacity: 240–450 μg/dL; Transferrin saturation: average 25%. [6] Reference ranges depend on multiple factors like age, sex, race and test devices. Most laboratories define “normal” as max. 30% for female and max. 45% for male ...
Just 1½ cups of Cheerios provides 12.6 mg of iron, about 70% of the daily recommendation, while 1¼ cups of Kellogg’s Special K delivers 10.9 mg of iron, about 60% of the daily value.
The normal range for hemoglobin is 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for women. [6] Low hemoglobin indicates anemia but will be normal for LID. [5] Normal serum iron is between 60 and 170 micrograms per deciliter (μg/dL). [7] Normal total iron-binding capacity for both sexes is 240 to 450 μg/dL. [6]
Infants, toddlers, and pregnant women have higher than average needs. Increased iron intake is also needed to offset blood losses due to digestive tract issues, frequent blood donations, or heavy menstrual periods. [74] Iron is an essential part of hemoglobin, and low iron levels result in decreased incorporation of hemoglobin into red blood cells.
[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 ...
