Reference range: |
Altitude-Related Reference Ranges for Soluble Transferrin Receptor, Serum African American 10.6-29.9 mmol living at low altitude, 12.5-31.8 mmol living at high altitude. Non-African American 8.8-28.1 mmol living at low altitude, 10.7-30 living at high altitude Clinical cutoff values (2) Iron deficiency anemia - Greater than ULRR (even during acute response to infection/inflammation). Hyperplastic Erythropoiesis: Greater than ULRR Ineffective Erythropoiesis: Grater than ULRR (e.g. thalassemia, megaloblastic or sideroblastic anemia) Effective increased: Greater than ULRR. Erythropoiesis (e.g., hemolytic anemia with an elevated reticulocyte count; recent blood donation; recent blood loss; last trimester of pregnancy) ULRR=Upper Limit of Reference Range for specific population (e.g., 29.9 nmol/L for African-Americans living <1000 feet above sea level).
