The kidney and, to a lesser extent, the liver both manufacture the glycoprotein hormone erythropoietin (EPO). EPO is a key erythropoiesis regulator and is crucial in preventing RBC oxidation. The EPO test aids in the diagnosis of a number of illnesses, including polycythemia and anaemia. This test also helps predict and track anaemic patients’ responses to recombinant EPO therapy. Elevated EPO levels are present in patients with secondary polycythemia, a disease in which the number of RBCs rises. EPO deficiency is present in polycythemia vera, severe anaemia, and chronic kidney failure. Order this test and pay a little cost for Free Sample Collection at Home.
