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).
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
How quickly can I get tested?
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
