Erythropoietin (EPO) is a hormone produced primarily by the kidneys. It is very important in the production of red blood cells (RBCs), which carry oxygen from the lungs to the rest of the body. The erythropoietin testing helps to measure the amount of erythropoietin in the blood.
The normal range of EPO is 2.6 to 18.5 milliunits per milliliter (mU/mL).
Increased EPO levels may indicate
- Secondary polycythemia
Decreased EPO levels may indicate
- Chronic kidney failure
- Anemia of chronic disease
- Polycythemia vera
