Polycythemia is an increase in the number of red blood cells in the blood. Accordingly, the treatment of polycythemia vera is mainly to reduce the consistency of the blood and prevent bleeding and clotting. One of these methods is to draw blood to reduce the number of red blood cells.

Erythropoietin is a glycoprotein produced by juxtaglomerular cells in response to tissue hypoxia, specifically stimulating red blood cell production in the bone marrow. Therefore, the Erythropoietin quantitative test will help doctors in diagnosing anemias related to red blood cell abnormalities.
