What is an EPO blood test?
What is an EPO blood test?
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 does a high EPO level mean?
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 a normal EPO level?
The normal range is 2.6 to 18.5 milliunits per milliliter (mU/mL).
When is EPO indicated?
Erythropoietin is used in many clinical settings. The most common use is in people with anemia (low blood count) related to kidney dysfunction. When the kidneys are not properly functioning, they produce less than normal amounts of erythropoietin, which can lead to low red blood cell production, or anemia.
How long does EPO test take?
The erythropoietin level test is quick, with blood drawn from your arm. You can get results in two to three days, but your lab may take longer. SOURCES: Mayo Clinic: “Polycythemia Vera,” “Complete blood count (CBC),” “Bone marrow biopsy and aspiration.”
How long does EPO stay in system?
EPO is undetectable in urine after 3–4 days of injection.
Can EPO be detected?
EPO, or erythropoietin, is a natural substance produced within the kidneys that stimulates the creation of new red blood cells. Blood-boosting drugs like EPO, if injected, are only detectable in the urine or blood for a short window of time.
What does EPO do to the body?
EPO is a peptide hormone that is produced naturally by the human body. EPO is released from the kidneys and acts on the bone marrow to stimulate red blood cell production. An increase in red blood cells improves the amount of oxygen that the blood can carry to the body’s muscles.
How is EPO test done?
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.
Does EPO really work?
EPO may not improve cycling performance at all, according to new scientific research. The banned drug increases the number of oxygen-carrying cells in the blood but a new study has raised doubts that it actually helps cyclists. Half of the cyclists were injected with the drug and half with a placebo.
