- Serum Ferritin Level
Ferritin is the measurement of the amount of iron that is available in the body, with the amount found in the blood equaling the amount that is stored within the body and available for use. Low blood levels are seen in people with iron-deficient anemia; high blood levels are seen people who have received blood transfusions, hemochromatosis, iron poisoning, hemolytic anemia, hepatitis, or autoimmune diseases. Iron levels can also be elevated due to acute illnesses, but these levels do not indicate the amount of stored iron available for use within the body.
