Fructosamine. A new parameter for diagnosis and metabolic control in diabetic dogs and cats.

Fructosamines are glycated serum proteins that, depending on their life span, reflect glycemic control over the previous 2 to 3 weeks. The nitroblue tetrazolium reduction method adapted to auto analysis appeared to be a practical means to assay fructosamine quickly, economically, and accurately. The upper limit of the reference range is 374 mumol/L in dogs (95% percentile) and 340 mumol/L in cats (95% percentile).
