Following agglutination, the Soluble transferrin receptor (sTfR) concentrations are inversely related to iron status; sTfR elevates in response to iron deficiency and decreases in response to iron repletion. Reticulocyte haemoglobin content (<29 pg) is an alternative.14 Red cell zinc protoporphyrin, soluble transferrin receptor, and the soluble transferrin receptor log ferritin ratio have been proposed as markers of functional iron deficiency. Soluble transferrin receptor Point-of-care testing Portable diagnostics 1. Conclusion: The ratio of soluble transferrin receptor to ferritin was lower in higher stages of chronic kidney disease. Soluble Transferrin Receptor (sTfR) ELISA kits have been introduced as a promising new diagnostic tool for differentiating between iron deficiency anemia (IDA) and anemia of chronic disease (ACD). When body cells are low in iron, the body produces more transferrin receptor. Camaschella (2019) states that low serum ferritin levels are the hallmark of absolute iron deficiency, reflecting exhausted stores. A carbonate (CO) has to be present to help attract iron to transferrin by creating opposing repulsive charges. MiChart Code. Plasma membrane-bound transferrin receptor is released by proteolytic cleavage of the extracellular domain, resulting in the formation of a truncated soluble transferrin receptor (sTfR) that circulates freely in the blood. In healthy people, about one-third of the binding sites on transferrin are used to transport iron. 2 - 4 days. Hence, the correlation between the sTfR ratio and the sTfR/log ferritin ratio with conventional iron status parameters in regular hemodialysis patients is necessary to be evaluated. This test measures the amount of soluble transferrin receptors to help detect and evaluate iron deficiency and aid in the diagnosis of iron deficiency anemia. serum soluble transferrin receptor levels and frequency of attacks.
