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 ...
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 ...
Transferrin (mg/dL) = 0.8 x TIBC (μg of iron/dL) – 43; Transferrin (mg/dL) = 0.7 x TIBC (μg of iron/dL) To measure TIBC in the blood is less expensive than a direct measurement of transferrin. [4] [5] The TIBC should not be confused with the unsaturated iron-binding capacity or UIBC (LOINC 2501-5, 22753-8 & 35216-1). The UIBC is calculated ...
Normal total iron-binding capacity for both sexes is 240 to 450 μg/dL. [6] 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 ng/mL for men and 15 to 150 ng/mL for women. [8] Low levels (< 12 ng/mL) are specific for iron ...
An example reference range for transferrin is 204–360 mg/dL. [30] Laboratory test results should always be interpreted using the reference range provided by the laboratory that performed the test [citation needed].

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 .
