title: [The fructosamine test for the determination of nonenzymatic glycosylated serum proteins. A critical inspection of the method].
abstract: A modification of the original method of R.A. Johnson et al. for nonenzymatically glycated serum proteins (fructosamine test) is described. Problems of performance and optimization of the method as well as of calibration and the influence of protein composition on the results are discussed. Measuring is manually performed after a 8 min preincubation interval over a 1 min's period using the spectrophotometer "Spekol 220". Interserial precision was 3.2%. First clinical results demonstrate the possibility to assess glycemic control in type 1 diabetic patients over a integrated time interval.
