Transferrin receptor (TfR) is a transmembrane glycoprotein. Soluble transferrin receptor levels in plasma are elevated if there is increased iron demand due to Iron deficiency, increased erythropoiesis (eg, Haemolysis) or dyserythropoiesis (eg, Megaloblastic anaemia), regardless of other, coexistent states. Some have reported that sTfR is useful in the differential diagnosis of IDA and anaemia of chronic disease or inflammation (ACD) 1.

Soluble transferrin receptor conventionally refers to the cleaved extracellular portion of transferrin receptor 1 that is released into serum.This receptor is a protein dimer of two identical subunits, linked together by two pairs of disulfide bonds.Its molecular mass 190,000 Dalton. Soluble Transferrin Receptor - Soluble Transferrin Receptor (sTFR) values can be within normal limits over a broad range of body iron stores and is elevated only when there is functional (i.e. Soluble transferrin receptors (sTfRs) are proteins found in the blood that are cleaved from the membrane-bound transferrin receptors found on nearly all cells [42]. 3.2.13 Soluble Transferrin Receptor. Increased levels of sTfRs are found in patients with increased erythropoiesis and iron deficiency. It is not a routine test but may be ordered if other tests that evaluate the amount of iron in the body do not provide conclusive information. Soluble transferrin receptor arises from proteolysis of the intact protein on the cell surface, leading to monomers that can be measured in plasma and serum. cellular) iron deficiency. Soluble transferrin receptor (sTfR), one of the main regulators of cellular iron homeostasis, is the truncated form of the tissue receptor that is encoded by the human TfR gene (chromosome 3). sTfR levels have been found to increase in iron-deficient erythropoiesis and iron deficiency anaemia (IDA). The serum concentration of sTfR is related to tissue receptor expression and therefore provides a clinical measure of the potential for cell proliferation (erythropoiesis) [42] .

The soluble transferrin receptor test is not a routinely order test, but since it is not an acute phase reactant, it may be ordered as an alternative to ferritin to evaluate stored iron when a chronic illness is present or suspected. A truncated extracellular form of the membrane transferrin receptor, soluble transferrin receptor (sTfR) is a marker of iron status and erythropoiesis. A soluble form of the TfR (sTfR) has been identified in animal and human serum.

The erythroblasts rather than reticulocytes are the main source of serum sTfR. Online conversion calculator for many types of measurement units in laboratory and medicine Soluble Transferrin Receptor (sTfR), sTfR, Transferrin Receptor, TfR, Serum Transferrin Receptors

Transferrin receptors, which are blood proteins, may be elevated in persons with iron deficiency.

Transferrin receptor testing is used to measure the level of soluble transferrin receptors, thereby aiding in the evaluation of iron deficiency and in the diagnosis of iron-deficiency anemia.. The soluble transferrin receptor (sTfR) immunoassay should not be used for the routine clinical evaluation of patients for iron status when ferritin immunoassay (FERR / Ferritin, Serum) would be appropriate, such as in the absence of confounding pathologies (inflammation, infection, chronic disease, or malignancy). Soluble transferrin receptor (sTfR) had been suggested as an indicator for iron deficiency. As a result, these sTFRs are released into the blood stream. The reference range of transferrin receptor varies by sex in adults, as follows:

Through proteolysis, TfR produces soluble transferrin receptor (sTfR) in the serum, whose concentration is proportional to the TfR concentration. No study has investigated the meaning of high sTfR as the only positive marker of iron deficiency anemia (IDA) caused by gastrointestinal tract (GIT) bleeding in hospitalized patients. Soluble Transferrin Receptor (sTfR) conversion to nmol/L, mg/L, mg/dL, mg/100mL, mg%, µg/mL. A truncated extracellular form of the membrane transferrin receptor, soluble transferrin receptor (sTfR) is a marker of iron status and erythropoiesis. Also known as CD71 and TfR1, transferrin receptor is necessary to regulate iron transport into cells from transferrin by receptor mediated endocytosis. Cellular iron uptake is mediated by a specific receptor for transferrin. Transferrin is a protein present in blood that binds to iron. When the number of complexes decrease, the number of vacant sTFRs increase. The soluble transferrin receptor (sTfR) test is primarily ordered to help distinguish between anemia that is caused by iron deficiency and anemia that is caused by inflammation or a chronic illness (so-called anemia of chronic disease or inflammation). This bound complex then binds to Soluble Transferrin Receptors (sTFRs) on cells. The soluble transferrin receptor (sTfR) has been introduced as a promising new diagnostic tool for differentiating between iron deficiency anemia (IDA) and anemia of chronic disease (ACD) ()()().The circulating sTfR concentration is proportional to cellular expression of the membrane-associated TfR and increases with increased cellular iron needs and cellular proliferation ().
