Transferrin
Here’s what it reflects — and what to do about it.

What is Transferrin?
The main protein that carries iron through your blood, and this test measures how much of it you have.
Transferrin acts like a delivery truck that moves iron around your body. Its level, together with iron tests, can be associated with how much iron your body has in store. A higher transferrin can be associated with low iron, while a lower level can be associated with other nutritional or inflammatory states. It is commonly looked at as part of an iron-status workup.
