Haemoglobin A2 level in pregnancy

The haemoglobin A(2) level was measured in 217 pregnant and 137 non-pregnant patients. Twenty-eight patients were reinvestigated at least six weeks after delivery. There was no significant difference in the mean haemoglobin A(2) level in pregnancy (2.4 +/- 0.8%) and the mean haemoglobin A(2) level in the non-pregnant controls (2.3 +/- 0.6%). In all anaemic patients whose A(2) level was raised in pregnancy the level remained elevated after delivery.
