Erythropoietin test

The erythropoietin test measures the amount of a hormone called erythropoietin (EPO) in blood.

The hormone tells stem cells in the bone marrow to make more red blood cells. EPO is made by cells in the kidney. These cells release more EPO when blood oxygen level is low.

 

Why the Test is performed?

This test may be used to help determine the cause of anemia, polycythemia (high red blood cell count) or other bone marrow disorders.

A change in red blood cells will affect the release of EPO. For example, persons with anemia have too few red blood cells, so more EPO is produced.
