Iron deficiency anemia can be diagnosed through several hematological and biochemical biomarkers including Hb, mean cell volume (MCV), mean cell hemoglobin (MCH), red cell distribution width (RDW), serum ferritin, serum iron, transferrin saturation (TS), total iron binding capacity (TIBC), and soluble transferrin receptor (sTfR) [11]. Here, TFRC is linked to Iron deficiency anemia.
