Normal: 250 to 300 mg/dL
Like albumin and prealbumin, transferrin is also synthesized by the liver. Transferrin is a visceral protein which serves as the transport protein for iron in the plasma. Transferrin has an intermediate half-life, 8 to 10 days, and therefore changes in nutrient intake or requirements, especially protein, are reflected in the transferrin level within a week.
Low transferrin levels: Less than 250 mg/dL
Low transferrin levels are not associated with specific symptoms or signs.
Mild deficit: <200 mg/dl
Moderate deficit: 100-199 mg/dl
Severe deficit: <100 mg/dl
Optimal re-feeding leads to a gradual increase in serum transferrin.
