WHAT IS BEING TESTED IN IRON AND TRANSFERRIN AND TIBC AND FERRITIN

Serum iron, total iron-binding capacity (TIBC), and/or transferrin tests are ordered mostly all together and after that transferrin saturations can be calculated which provide information regarding the how much iron is being carried in the blood. Ferritin confers the total iron stores in the patient .
