Self-monitoring of blood glucose in women attending a diabetes and pregnancy clinic: Accuracy in reporting blood glucose values and fulfilment of scheduled timing

Reflectance meters with memory were used to test the accuracy in timing and reporting of self-monitored blood glucose in 19 women attending a Diabetes and Pregnancy Clinic. Although 30.2% reported blood glucose measurements had undergone some kind of manipulation, mean meter and autolog blood glucose values did not differ. Manipulations were more frequent in abnormal blood glucose values and resulted in normalization of 23.7% pathological values. Inaccuracies in self-measurement timing also were observed; 35.2% records deviated from scheduled timing by 30 min or more.
