What is a Reticulocyte Count and Erythropoietin (EPO) Test?
The Reticulocyte Count, Automated and Erythropoietin test measures the number of reticulocytes (immature red blood cells) in your blood and the level of erythropoietin (a hormone that regulates red blood cell production). These tests help evaluate your body’s ability to produce red blood cells.
Importance of These Tests
The reticulocyte count test is crucial in diagnosing and monitoring conditions like anemia, bone marrow disorders, and response to treatments like chemotherapy. Erythropoietin levels are essential in diagnosing kidney disease, and certain types of anemia, and evaluating the body’s oxygen-carrying capacity.
Why Consider Ordering These Tests?
Ordering these tests can provide valuable insights into your health, especially if you experience symptoms like fatigue, weakness, or shortness of breath. Early detection and monitoring can lead to better management and treatment outcomes for various health conditions.

What do low and high levels mean?
High reticulocyte levels may indicate increased red blood cell production due to blood loss or hemolytic anemia while low levels can suggest bone marrow suppression or chronic diseases. High erythropoietin levels may indicate conditions like polycythemia or tumors while low levels can point to chronic kidney disease or anemia.
What are the signs and symptoms of the issues these tests detect?
Symptoms can include fatigue, weakness, shortness of breath, pale skin, and dizziness. These symptoms can be related to anemia, bone marrow disorders, or kidney disease.
