A recent study demonstrated that plasma transferrin does not provide supplementary information when co-ordered with iron studies (serum iron, total iron-binding capacity) and ferritin tests in anemic patients.9 Furthermore, transferrin levels exhibit low accuracy in diagnosing and treating iron deficiency anemia.10,11 As a result, plasma transferrin is considered redundant and overused in the context of iron deficiency anemia. This evidence concerns the gene TF and Iron deficiency anemia.
