Transferrin LabCorp

Transferrin levels have been seen to increase in iron deficiency anemia. It is decreased in chronic inflammatory states, hereditary atransferrinemia, some instances of acquired liver disease, neoplasia, and renal disease. Transferrin is an index of nutritional status. Transferrin is responsible for 50-70% of the iron binding capacity of blood serum. Since other proteins may bind to iron, transferrin is not the same as total iron binding capacity (TIBC). Transferrin is an iron transport protein receiving and binding to iron for delivery to receptors at recipient cells.
