Abstract
As a cause of anemia in patient with chronic renal failure, shortened RBC survival is known. RBC deformability that may have a deep concerning of RBC survival rate, reduced compared with normal control group. (p<0.01) In 11 cases of hemodialyzed patients who have no transfusion episode, RBC deformability correlates between blood hemoglobin concentration. (r=0.67 p<0.01)
