What is Erythropoietin?
Erythropoietin (EPO) is a hormone produced in the kidneys. The existence of this hormone has been known since 1906, when scientists first started isolating it, and since the 1980s, a recombinant version of the hormone known as Epogen or Betapoietin has been available for use in medical treatment. People can use erythropoietin in treatments for anemia, typically in the case of anemia caused by chemotherapy, chronic kidney disease, or heart failure. A doctor usually supervises use of the hormone, with periodic blood tests to monitor patient progress.
