[Albumin or protein standardized fructosamine-plus, 2 new indices for evaluating diabetic metabolic status].

We have evaluated a new method for the determination of glycated serum proteins (fructosamines), which are elevated in diabetics. In accordance with earlier findings fructosamine depends not only on mean blood glucose but also on albumin- and total protein concentrations. Therefore fructosamine is not useful as an index of diabetic blood glucose control without consideration of an individuals albumin- or protein-concentration. We propose albumin- or protein-standardized fructosamines as new indices of diabetic control.
