HelpTest Code LAB829 Iron and TIBC (Total Iron Binding Capacity)
Useful For
Alterations in iron and total iron binding capacity (TIBC) levels result from changes in iron intake, absorption, storage, and release mechanisms. Such changes are indicative of a wide range of dysfunctions including
anemias, nephrosis, cirrhosis and hepatitis. Both iron and TIBC measurements are important for definitive diagnosis because they are interrelated. Tietz has presented a summary of these relationships and the patterns of iron/total iron binding capacity associated with various disease states.
1. Serum iron is increased with oral contraceptives and in hemosiderosis, hemolytic anemias, especially thalassemia, sideroachrestic anemias, hepatitis, acute hepatic necrosis and hemochromatosis.
2. Serum iron is decreased with iron-dextran administration, insufficient dietary iron, chronic blood loss, inadequate absorption of iron and impaired release of iron stores as in inflammation, infection and chronic diseases.
