Clinical Significance
Transferrin levels rise with iron deficiency and fall in cases of iron overload. An increase in transferrin is seen in
iron deficiency anemia. It may also be increased late in pregnancy and in women on oral contraceptives. It is
decreased in conditions associated with increased protein loss, such as nephrotic syndrome, chronic renal failure,
severe burns, and protein-deficiency states and in severe liver disease. Transferrin is a negative acute-phase protein
and will be decreased during any inflammatory state or severe illness.
