[2,3-diphosphoglycerate and glycosylated hemoglobin in diabetes mellitus].

Large amounts of intraerythrocyte 2-3 diphosphoglycerate (2-3 DPG) increase red cell oxygen-releasing capacity. Since glycosylated hemoglobins, found in higher percentages in diabetics, have an increased oxygen affinity, 2-3 DPG concentration was assayed in 12 diabetics (4 I.D.
