Why Do Red Blood Cells Produce Erythropoietin

Satisfactory Essays

• Kidneys produce erythropoietin (EPO). This erythropoietin signals the bone marrow to produce red blood cells, which carries oxygen throughout the body.
• If kidneys are damaged, they do not make enough EPO, which results to anemia. When blood has fewer red blood cells, there’s less oxygen in the body.
Hemoglobin is the red blood cell that carries oxygen. It is used as the standard measurement for assessing anemia.
• Iron is critical for hemoglobin production. Iron status test reflect the level of iron stored in tissue or the adequacy of iron for erythropoiesis.
• Serum ferritin is the only available blood marker for iron storage. It is affected by inflammation and is an acute phase reactant. It is used with caution especially to those patients
