Verified self-monitored blood glucose data versus glycosylated hemoglobin and glycosylated serum protein as a means of redicting short- and long-term metabolic control in gestational diabetes

Glycosylated hemoglobin and glycosylated serum protein have been suggested as tools for evaluation of long- and short-term glycemic control, respectively. Twenty-six patients with gestational diabetes were prospectively studied to determine the relationship of glycosylated hemoglobin and glycosylated serum protein to metabolic control. To verify the accuracy of blood glucose data, a memory-based reflectance meter was used for subjects with gestational diabetes who tested 6.5 ± 1 times per day. Our analysis revealed that despite a statistically positive correlation between glycosylated hemoglobin, glycosylated serum protein, and verified data, their use as a clinical tool is limited because of their poor predictability.
