- Serum iron, TIBC and transferrin are usually ordered together and, subsequently, the transferrin saturation can be determined and used to assess how much iron is being carried in the blood.
- Low iron may meet nutrient deficiency or chronic illness.
- Treatment is based on etiology of elevation.
- High Iron – Increased levels may be seen in alcohol abuse, acute hepatitis, and infections. In severe cases of hemochromatosis, periodic removal of a prescribed amount of blood, also known as therapeutic phlebotomy, may be necessary.
- Low Iron – supplemental iron
