Erythropoietin (EPO) test
What is being analysed in this test?
This test analyses the amount of Erythropoietin (EPO) in the blood. is a hormone primarily produced by the kidneys, although a small amount is also produced by the liver. It plays a crucial role in the production of red blood cells (erythropoiesis) by stimulating the bone marrow.
What does the result mean?
The result of an erythropoietin analysis indicates the level of EPO present in the blood. Abnormal levels can suggest various medical conditions affecting the kidneys, bone marrow, or other parts of the body.
Why perform the analysis?
An erythropoietin analysis is performed to assess the body's ability to produce red blood cells adequately. It helps diagnose and monitor conditions such as anaemia, chronic kidney disease, polycythaemia, and certain cancers.
When should the analysis be done?
An erythropoietin analysis is typically ordered when a healthcare provider suspects an underlying condition affecting red blood cell production. This may include symptoms such as fatigue, weakness, shortness of breath, or abnormal blood counts.
What sample is required?
A blood sample is required for erythropoietin analysis. This sample is usually drawn from a vein in the arm using a needle.
Is any prior preparation necessary?
Generally, no specific preparation is required for an erythropoietin analysis. However, it's essential to follow any instructions provided by the healthcare provider, such as fasting requirements, if applicable.
How is it used?
The results of an erythropoietin analysis are interpreted alongside other clinical information to help diagnose and monitor conditions affecting red blood cell production. Treatment decisions may be based on these results.
What are the normal values?
Normal values for erythropoietin can vary depending on factors such as age, gender, and altitude. However, typical reference ranges fall between 4 and 24 mU/mL (milliunits per millilitre).

Erythropoietin Level (mU/mL)
Interpretation
Less than 4
Low erythropoietin levels
4 - 24
Normal erythropoietin levels
Greater than 24
Elevated erythropoietin levels
This table provides a reference for interpreting erythropoietin levels in clinical practice.
Always consult with a healthcare provider for proper interpretation and diagnosis based on individual medical history
What do abnormal values indicate?
High EPO levels: Elevated erythropoietin levels may indicate conditions such as chronic kidney disease, certain types of anaemia (e.g., secondary polycythemia), or hypoxia (low oxygen levels). Low EPO levels: Reduced erythropoietin levels may suggest conditions such as anaemia of chronic disease, bone marrow disorders, or primary polycythemia.
