A patient on renal dialysis has a low rbc count what hormone secreted by the kidney can be assumed to deficient?

The hormone that can be assumed to be deficient in a patient on renal dialysis with a low red blood cell count is erythropoietin (EPO). EPO is a hormone produced by the kidneys that stimulates the production of red blood cells in the bone marrow. In the case of renal dialysis, the kidneys may not be functioning properly, leading to decreased production of EPO and subsequently a low red blood cell count (anemia). This condition is known as anemia of chronic kidney disease (CKD) or renal anemia. Administration of synthetic EPO is often necessary in patients with CKD to correct the anemia.
