What is Unsaturated Iron-Binding Capacity (UIBC)?
Unsaturated iron-binding capacity (UIBC) measures the portion of transferrin in your blood that is not currently bound to iron. Transferrin is the main protein that transports iron throughout your body.
Under normal conditions, only about one-third of transferrin is saturated with iron. The remaining two-thirds represents the reserve capacity available to bind additional iron. UIBC measures this unused capacity.
UIBC is closely related to total iron-binding capacity (TIBC). The formula is: TIBC = UIBC + serum iron. Together with serum iron and ferritin, UIBC helps create a complete picture of how your body manages iron.
Where Does Unsaturated Iron-Binding Capacity (UIBC) Come From?
Transferrin is produced primarily by the liver and released into the bloodstream. When iron stores are low, the liver increases transferrin production to maximize iron capture from the diet.
