Transferrin

Brown clotted serum, gel barrier or orange lithium heparin

TestTransferrin
Common AbbreviationsTRA
ProfileIron Studies/ Transferrin saturation
Tube typeBrown clotted serum, gel barrier or orange lithium heparin
Clinical IndicationMeasurement of plasma transferrin levels is useful in the differential diagnosis of anaemia and will rise with iron deficiency anaemia. In congenital atransferrinaemia, a very low level of transferrin is accompanied by iron overload and a severe hypochromic anaemia resistant to iron therapy. High levels of transferrin occur in pregnancy and during oestrogen administration. It is decreased in conditions that are associated with increased protein loss such as nephritic syndrome, protein-deficiency states and in chronic liver disease. Transferrin is a negative acute phase reactant and will decrease during any inflammatory state or malignancy. Transferrin is used in conjunction with iron to calculate transferring saturation.
