Overview:

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.
