Erythropoietin is a hormone produced by the kidneys that stimulates red blood cell production. Abnormal levels can be caused by conditions like kidney disease, anemia, or tumors.
Erythropoietin, often abbreviated as EPO, is a hormone primarily produced by the kidneys. Its main function is to stimulate the production of red blood cells in the bone marrow, which are responsible for carrying oxygen to the body’s tissues. This process is crucial for maintaining healthy oxygen levels and ensuring the proper functioning of vital organs.
When the body senses a shortage of oxygen, such as during high altitudes or in cases of anemia, the kidneys produce more EPO to boost red blood cell production and restore oxygen balance.
Erythropoietin is also a key biomarker used in diagnosing and managing various health conditions. Measuring EPO levels can help determine the cause of anemia, evaluate kidney function, and identify other medical conditions affecting red blood cell production.
EPO testing is typically recommended when a doctor suspects an imbalance in red blood cell production, which could be due to several health conditions. Below are common scenarios when EPO testing may be ordered:
Erythropoietin levels are measured through a blood test. A sample of venous blood is collected, typically from a vein in the arm, and then analyzed in a laboratory using specialized techniques. The most common method used to measure EPO levels is the immunochemiluminescence assay.
This test is often ordered alongside other blood tests, such as:
Special preparations before the test include:
For adults, normal erythropoietin levels typically range between 2.6 and 18.5 mlU/mL.
Note: The units of measurement and the normal ranges can differ depending on the laboratory and the specific methods used.

High EPO levels can indicate the body is overproducing red blood cells or compensating for low oxygen levels. Below are common causes of elevated EPO levels:
To help manage high erythropoietin levels, consider the following tips:
Low EPO levels often point to issues with red blood cell production, leading to insufficient oxygen supply to the body. Here are some of the common causes:
If you have low erythropoietin levels, consider the following management strategies:
Depending on the cause of your abnormal erythropoietin levels, you may need to consult with different medical specialists:
Regular check-ups and following the advice of your healthcare team are essential for managing any condition that affects erythropoietin levels.
While there are no direct lifestyle changes to increase erythropoietin production, staying active, maintaining good kidney health, and eating iron-rich foods can support red blood cell production and improve overall oxygen levels in your body.
Absolutely. Low EPO levels can lead to anemia, which results in reduced oxygen supply to tissues, making you feel fatigued, weak, and less energetic in your daily activities.
