What is Soluble Transferrin Receptor (sTfR)?
The Soluble Transferrin Receptor (sTfR) is a biomarker that circulates in the blood and plays a role in iron transport in the body. It reflects the amount of transferrin receptor that detaches from the cell surface, which is directly related to the body's iron requirement.
Why should you have sTfR tested?
Testing sTfR is useful for assessing the body's iron status, especially in cases where other tests such as serum iron or ferritin may not provide a clear picture. It is particularly useful in diagnosing iron deficiency or in distinguishing iron deficiency anemia from other forms of anemia.
What does it indicate?
An sTfR test indicates the amount of iron available for red blood cell production. It helps determine whether the body has enough iron for normal blood formation and reveals iron deficiency before it becomes apparent in standard blood tests.
What does a high sTfR level mean?
A high level of sTfR indicates an increased need for iron or a lack of iron in the body. This may suggest iron deficiency anemia or increased erythropoiesis (red blood cell production).
