soluble transferrin receptor

Abbreviation: sTfR
A membrane-bound receptor expressed on the surfaces of cells that take up iron from the blood. Levels of this receptor are increased in iron-deficiency anemia. Measurement of circulating levels of the receptor are very useful in the diagnosis of iron deficiency in patients who also have anemia of chronic disease.

Increased erythropoietic activity causes TfR synthesis to be upregulated and thereby increase the soluble transferrin receptor (sTfR) level.
Serum soluble transferrin receptor reflects erythropoiesis but not iron availability in erythropoietin-treated chronic hemodialysis patients.
Conclusion: The ratio of soluble transferrin receptor to ferritin was lower in higher stages of chronic kidney disease.

When a CHr <28 pg was used for identification of ID and FID in anemic patients, the values of ferritin, soluble transferrin receptor (sTfR), and the sTfR-F index (sTfR/ log ferritin) (4) performed significantly better in patients without APR [based on a C-reactive protein (CRP) cutoff of 5 mg/L].
The introduction of new laboratory tests, especially soluble transferrin receptor (sTfR), has enabled the identification of storage iron depletion, iron-deficient erythropoiesis, iron deficiency anemia (IDA), and functional ID as readily distinguishable clinical conditions (1-5).
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) (1-3).
Because the soluble transferrin receptor (sTfR) concentration is not influenced by acute-phase reactions, it remains within reference values in patients with anemia of chronic disease.
Serum soluble transferrin receptor (sTfR) has been established in recent years as a powerful tool for detecting iron deficiency (ID) in adults, especially in distinguishing between iron deficiency anemia (IDA) and anemia of chronic disease (1-8).
