Serum Iron
Alternate Names : Iron Level (Fe)
What do the test results mean?
Normal serum iron levels are:
Men: 65 to 176 g/dL (micrograms/deciliter)
Women: 50 to 170 g/dL
Newborns: 100 to 250 g/dL
Children: 50 to 120 g/dL
Very high levels of serum iron can indicate a number of conditions. These include:
hemolytic anemia, which occurs when hemoglobin leaks out of red blood cells
hemosiderosis or hemochromatosis, which are genetic disorders that cause iron to build up in the body
iron poisoning, caused by ingestion of too much iron
a large blood transfusion
lead poisoning, caused by accidental ingestion of lead
liver problems, such as hepatitis or cirrhosis
Low serum iron levels may be a sign of:
chronic blood loss, such as gastrointestinal bleeding
a diet low in iron
iron deficiency anemia
poor absorption of iron from the digestive tract
third-trimester pregnancy
tumor growth
