What is erythropoietin test?
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.
What does high erythropoietin level indicate?
Having higher levels of erythropoietin in the blood may be a sign that the body is not getting enough oxygen, however. This may be due to a low red blood cell count from anemia or another condition. On the other hand, low levels of erythropoietin in the blood in someone with anemia may be a sign of other issues.
How do you test for EPO?
A blood screening was performed first, and a urine test was then used to confirm possible use of EPO. In June 2003, WADA’s Executive Committee accepted the results of an independent report stating that urine tests alone can be used to detect the presence of recombinant EPO.
What is EPO blood?
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 normal EPO levels?
Normal Results The normal range is 2.6 to 18.5 milliunits per milliliter (mU/mL).
What organ is responsible for erythropoietin?
Erythropoietin, also known as EPO, is a hormone that the kidneys produce to stimulate production and maintenance of crucial red blood cells. The hormone does this in two ways: First, it stimulates bone marrow cells to produce red blood cells.
What is a normal erythropoietin level?
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.
What levels indicate polycythemia?
In polycythemia, the levels of hemoglobin (Hgb), hematocrit (Hct), or the red blood cell (RBC) count may be elevated when measured in the complete blood count (CBC), as compared to normal. Hemoglobin levels greater than 16.5 g/dL (grams per deciliter) in women and greater than 18.5 g/dL in men suggest polycythemia.
Is EPO detectable?
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.
