A normal range for serum iron in women is 50 to 150 micrograms per deciliter, according to WebMD. Total iron-binding capacity for women should fall between 250 and 450 micrograms per deciliter, while the transferrin saturation for women should range from 15 to 50 percent.
These reference ranges are useful in determining if a patient is suffering from iron deficiency anemia, hemolytic anemia, thalassemia, hemochromatosis or cirrhosis. The ranges can also be used in diagnosing lead poisoning, rheumatoid arthritis, iron supplement overuse, severe infections and kidney failure. Iron tests check the level of iron in the blood and can help medical professionals determine if the body is efficiently metabolizing iron, allowing for a more definitive diagnosis of certain medical conditions, according to WebMD.
