An erythropoietin (EPO) test is used primarily to help diagnose the cause of anemia. An EPO test is usually ordered in follow up to abnormal results on a complete blood count (CBC), such as a low red blood cell (RBC) count and low hemoglobin and hematocrit.
What would you suspect to find if someone has high blood erythropoietin levels?
Test results that show that a person with anemia has high erythropoietin levels may be a sign of a bone marrow disorder. Low or normal erythropoietin levels in a person with anemia may be a sign of kidney disease.
How do you interpret EPO levels?
The normal range for EPO levels can vary from 4 to 26 milliunits per liter (mU/mL). Higher-than-normal levels may mean you have anemia. In severe cases of anemia, EPO levels in the blood may be a thousand times higher than normal. Unusually low levels may be because of polycythemia vera.
What is the role of erythropoietin?
Erythropoietin is a hormone, produced mainly in the kidneys, which stimulates the production and maintenance of red blood cells.
How does erythropoietin work in the body?
In order to make red blood cells, the body maintains an adequate supply of erythropoietin (EPO), a hormone that is produced by the kidney. EPO helps make red blood cells. Having more red blood cells raises your hemoglobin levels.
What are side effects of erythropoietin?
Common side effects
- Allergic reaction. Rarely, some people have an allergic reaction to erythropoietin.
- Feeling sick or being sick. You may feel sick during treatment with erythropoietin.
- Diarrhoea.
- Blood clot risk.
- Headaches.
- High blood pressure.
- Muscle, joint or bone pain.
- Flu-like symptoms.
What triggers erythropoietin release?
The kidney cells that make EPO are specialized and are sensitive to low oxygen levels in the blood coming into the kidney. These cells release erythropoietin when the oxygen level is low in the kidney.
What is the normal erythropoietin?
The normal range is 2.6 to 18.5 milliunits per milliliter (mU/mL).
Why is erythropoietin banned?
The drug erythropoietin, often called EPO, is banned from sports because it is believed to enhance an athlete’s performance and give people who use it an unfair advantage over unenhanced competitors. EPO thickens a person’s blood, which can lead to an increased risk of clots.
What are the side effects of taking erythropoietin?
How quickly does erythropoietin work?
People with severe anemia usually feel very tired and sick. When epoetin begins to work, usually in about 6 weeks, most people start to feel better. Some people are able to be more active.
What are the major effects of erythropoietin?
Erythropoietin stimulates the bone marrow to produce more red blood cells. The resulting rise in red cells increases the oxygen-carrying capacity of the blood. As the prime regulator of red cell production, erythropoietin’s major functions are to: Promote the development of red blood cells.
Is EPO bad for you?
It is well known that EPO, by thickening the blood, leads to an increased risk of several deadly diseases, such as heart disease, stroke, and cerebral or pulmonary embolism. The misuse of recombinant human EPO may also lead to autoimmune diseases with serious health consequences.
What are the long term effects of erythropoietin?
“Long-term use of EPO can lead to an increased risk of heart attack, stroke and pulmonary emboli — blood clots in the lungs,” he added. “This increase in potential for developing such complications is directly linked with the duration of use of EPO.”
How does erythropoietin affect the body?
Why is EPO banned?
Summary: The drug erythropoietin, often called EPO, is banned from sports because it is believed to enhance an athlete’s performance and give people who use it an unfair advantage over unenhanced competitors. EPO thickens a person’s blood, which can lead to an increased risk of clots.

Can you buy EPO legally?
