Normal levels of glycosylated haemoglobin in pregnant Nigerian women.
Total glycosylated haemoglobin (HbA1) was measured in 16 healthy non-pregnant Nigerian women and in three groups of healthy women at various times during pregnancy. There was a statistically significant decrease in HbA1 in the first trimester. The values progressively increased thereafter and by term, the values were comparable to those in non-pregnant controls. The values were identical to those reported for caucasian women at similar stages of pregnancy.
