Clinical Significance
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. cellular) iron deficiency. It is usually not affected by chronic disease states, sTFR levels are about 6% higher in people in high altitudes (above 5200 ft/1600 m) and in African-Americans. Reference value may not apply to pregnant females and recent or frequent blood donors.
