Total Iron Binding Capacity is an approximate estimation of the serum transferrin level. Iron plays a principle role in producing red blood cells and is transported in the blood as transferrin, a major transport protein. TIBC is low with iron deficiency anemia and high with anemia of chronic disease. TIBC is also used to help confirm a diagnoses of iron overload, also known as hemochromatosis.
Test Preparation For Optimal Results:
If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
Disclaimer: A health care provider should evaluate a deviation from normal ranges.
