[Erythrocytic 2-3-diphosphoglycerate in diabetes mellitus].

Red cell 2-3 DPG concentration in diabetes mellitus has been found to be equal to normal. Red cell 2-3 DPG seems to be related to Hb concentration. There is an appreciable scatter of 2-3 DPG among healthy males and healthy females. Female diabetics have a red cell 2-3 DPG like male diabetics despite a significative lower Hb concentration. However, the conflicting data reported on the amount of 2-3 DPG in diabetic red cells could be referred to an unequal arrangement of males and females in control subjects and diabetics.
