Soluble Transferrin Receptor (sTfR)

The analysis of the soluble transferrin receptor is a blood test used to assess levels of the soluble transferrin receptor. This protein is associated with iron metabolism and can be useful in diagnosing and monitoring iron disorders, such as anemia and iron levels in the body. IntroLab laboratory in Belgrade offers reliable and accurate analysis of the soluble transferrin receptor, which is essential for your health.

More about the parameter

The soluble transferrin receptor is a form of the transferrin receptor that is released into the bloodstream. The transferrin receptor is a protein found on the surface of cells and plays a role in the binding and transport of iron. When erythrocytes break down, the soluble transferrin receptor is released into the blood. Its concentration in the blood can be related to the body’s iron status.

Elevated levels of the soluble transferrin receptor may indicate reduced iron levels or anemia, while decreased values may be associated with normal or increased iron levels. This analysis is used as an additional test in assessing iron metabolism and can provide important information for the diagnosis and monitoring of various conditions, and is also considered one of the blood tests for anemia.

Soluble transferrin receptor analysis – Indications

The analysis of the soluble transferrin receptor is usually recommended for individuals suspected of having an iron metabolism disorder or anemia. The decision to perform this analysis is made by a doctor based on clinical symptoms, other laboratory findings, and the patient’s medical history. If you have doubts or suspect that you have a problem with iron metabolism, it is advisable to consult with a qualified doctor who will assess whether the soluble transferrin receptor analysis is necessary in your case.

What does the sampling look like?

Sampling for the analysis of the soluble transferrin receptor is typically done through blood draw. The sampling procedure usually involves venipuncture, where a needle is used to puncture a vein in the forearm to collect a blood sample. Before taking the sample, the skin area is usually disinfected with an antiseptic solution, and then a needle is inserted into the vein to collect blood. The sample is then placed in a special tube or vial with an anticoagulant to prevent blood clotting. The analysis of the soluble transferrin receptor is then conducted.
