Effect of acute hyperglycaemia on the serum fructosamine and blood glycated haemoglobin concentrations in canine samples

The effect was studied of an acute and non-persistent hyperglycaemia on the serum fructosamine and blood glycated haemoglobin concentrations in canine samples. Five dogs were given glucose solution intravenously and blood sam ples were taken from each dog before and at 5, 15, 30, 60 and 120 min and 2 4 h after the infusion. There was an intense hyperglycaemia 5 min after the injection was given, but no statistically significant differences in the s erum fructosamine and glycated haemoglobin were observed. It was concluded that an acute and transient hyperglycaemia does not cause significant chang es in the glycated haemoglobin and fructosamine concentrations in healthy d ogs.
