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.
The increase in systemic iron levels becomes pathological in old age, ... cases the iron stores of an adult may reach 50 grams (10 times normal total body iron) or ...
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 ...

The study, which was published in JAMA, analyzed data on iron blood levels from more than 3,400 women and girls between the ages of 12 and 21 who participated in the National Health and Nutrition ...
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 nanograms per milliliter (ng/mL) for men and 15 to 150 ng/mL for women. [8]
