[Glycosylated hemoglobin (HbA1) in chemical gestational diabetic and diabetic pregnancy (author's transl)].

The authors have determined, by ionic resin exchange chromatographic method, HbA1 values in 16 chemical gestational diabetic pregnant, in 4 case with insulin dependent diabetes and 34 normal pregnant women. Statistical differences were found between normal's HbA1 mean values and clinical diabetics' but not with chemical gestational diabetics. HbA1 mean values in chemical gestational diabetics with diabetic familiarity were found statistically higher than normal subjects' values. Mothers with chemical gestational diabetic, who delivered newborn with less than 50th centile had HbA1 values significantly elevated.
