Reference Range:
Normal serum concentrations of erythropoietin for 95% of individuals with normal hematocrits range from 4-27 mU/mL. As the hematocrit is lowered by iron deficiency, aplastic or hemolytic anemia, the concentration of erythropoietin increases as shown in the graph below. In the absence of anemia, elevated concentrations are seen in renal tumors, as a manifestation of renal transplant rejection, and in secondary polycythemia. Low values may be observed in hemochromatosis. Decreased erythropoietin concentrations with an elevated hematocrit are observed in patients with polycythemia rubra vera, and with a decreased hematocrit in patients with HIV infection who are receiving AZT. Patients on AZT who have anemia and erythropoietin concentrations of less than or equal to 500 mU/mL, may benefit from therapy with recombinant EPO (NEJM 322:1488-1493, 1990).
