Transferrin saturation
Name transferrin_saturation_gprd
Chapter Diseases of the blood/Haematinics
Definition
Transferrin is the major iron-carrying protein in the blood. Instead of being measured directly the 'total iron-binding capacity' (TIBC) is measured, and the serum iron divided by TIBC is the transferrin saturation.

The value is a percentage and must be between 0 and 100.
