<prompt> What is the anemia usually associated with chronic renal failure?HypochromicMacrocyticNormochromic normocyticMicrocytic  <response>: The anemia of chronic renal failure is usually normochromic normocytic. Hematocrit often stas to decrease when the serum creatinine level reaches 200 to 300 mmolL 2 to 3 mgdl or when the glomerular filtration rate has decreased to about 20 to 30 mlmin. The etiology of the normochromic:normocytic anemia is probably a decreased synthesis of erythropoietin by the kidney. Ref: Bargman J.M., Skorecki K. 2012. Chapter 280. Chronic Kidney Disease. In D.L.
