There are different ways to measure iron levels. Here's why they matter for you:


Iron is important in transferring oxygen throughout the body using red blood cells. Iron is measured in the body when it is bound to transferrin, a protein that transfers iron.

Total Iron-Binding Capacity

Total Iron-Binding Capacity or TIBC is the total of all the available proteins in the body that are used for transporting iron around the body.


Ferritin allows iron to be stored in the body and it is measured to identify how much iron is stored in the body.

Transferrin Saturation

Transferrin Saturation is measured to identify how much iron is being transferred around the body via the protein transferrin.
