Erythropoietin test - Results

Alternative Names

Serum erythropoietin; EPO

Normal Values:

The normal range is 0-19 milliunits per milliliter (mU/mL).

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

What abnormal results mean:

Increased EPO levels may be due to secondary polycythemia, an overproduction of red blood cells that occurs in response to an event such as low blood oxygen levels. This may happen at high altitudes or, rarely, because of a tumor that releases EPO.

Lower-than-normal EPO levels may be seen in chronic kidney failure, anemia of chronic disease, or polycythemia vera.
