What does the Total Iron-Binding Capacity test measure?

Total Iron-Binding Capacity (TIBC) is a clinical biomarker used in vitamins-minerals assessment. Total iron-binding capacity reflects the blood's capacity to bind iron, largely determined by transferrin, the main iron-transport protein. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Total Iron-Binding Capacity?

Total iron-binding capacity reflects the blood's capacity to bind iron, largely determined by transferrin, the main iron-transport protein. TIBC rises when iron stores are low (the body upregulates transferrin) and falls in iron overload and chronic disease.

Why is Total Iron-Binding Capacity measured?

TIBC helps distinguish causes of abnormal iron status: a high TIBC supports iron deficiency, while a low or normal TIBC accompanies iron overload and the anaemia of chronic disease. With serum iron it yields transferrin saturation.
