2,3-diphosphoglycerate concentration in the red blood cells of anaemic pregnant women in various periods of pregnancy.

The purpose of this study was to examine the intraerythrocytic 2,3-diphosphoglycerate (2,3-DPG) concentration in anaemic (haemoglobin concentration below 10.5 g/100 ml blood) and in normal pregnant women (haemoglobin concentration above 12.5 g/100 ml blood). The authors showed that the 2,3-DPG concentration increased systematically between the 16th and 42nd weeks of pregnancy, both in the control group and in pregnant women with anaemia. However, in the group of anaemic pregnant women the 2,3-DPG concentration was higher in each stage of pregnancy.
