GENERAL NOTES



APPLICATION:  Diabetes mellitus: monitoring of glycaemia over previous 3 months.

INTERPRETATION:  The result reflects the average glucose concentration over the life of the red cells. Levels will be lower than appropriate for the degree of diabetic control in the presence of reticulocytosis or increased RBC turnover. In such patients, fructosamine is the preferred assay.
