what is tibc in blood work
Iron is transported in the blood as transferrin, a major transport protein. Transferrin carries 60-70% of the bodyâs iron. The total amount of iron bound to transferrin is referred to as total iron-binding capacity (TIBC). TIBC will help your doctor differentiate between different types of anemia. TIBC is high in iron deficiency anemia and low/normal with anemia of chronic disease. TIBC is also used to help doctors diagnose iron overload, which is called hemochromatosis. Low levels of iron are associated with iron deficiency anemia.
