Transferrin
What It Is
Transferrin is a protein that transports iron in the blood from sites of absorption to sites of use and storage.
Why It Matters
Transferrin levels help assess iron metabolism and differentiate between types of anaemia.
If Levels Are High
High transferrin indicates iron deficiency, as the body produces more to maximise iron capture.
If Levels Are Low
Low transferrin may indicate chronic disease, liver disease, or iron overload.
Preparation
Morning fasting sample preferred.
How Often to Test
As clinically indicated alongside iron studies.
