Iron (1040)

Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. Hemoglobin represents about two-thirds of the body's iron. If you don't have enough iron you can't make hemoglobin.

Methodology

Colorimetric

• 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.
