TIBC --> total iron binding capacity

(Science: biochemistry, haematology) A test that measures indirectly the transferrin level in the bloodstream.

transferrin is a protein that carries iron in the body. Normal values are 240 to 450 mcg/dl. This test is used to evaluate anaemia. Greater than normal total iron binding capacity can be seen in: iron deficiency anaemia, late pregnancy and polycythaemia vera.

Lower than normal total iron binding capacity can be seen in cirrhosis, sickle cell anaemia, hypoproteinaemia, pernicious anaemia and haemolytic anaemia. The use of birth control pills can lead to increased total iron binding capacity measurements.
