title: [Determination of fructosamine in chronic kidney diseases (dialysis-dependent patients)].
abstract: The serum fructosamine normal range was confirmed. Correction to protein or albumin did not significantly affect the results. Therefore, correction of fructosamine values from patients with normal protein and albumin values would not improve the clinical significance of fructosamine. Fructosamine concentrations of heparin plasma from non-diabetics also fell within the serum fructosamine normal range. The fructosamine concentration from non-diabetic dialysis patients was significantly higher and more widely distributed than that of the reference collective despite normal blood glucose concentration. Relating fructosamine to protein had no substantial effect, whereas the differences were even increased when fructosamine was related to albumin. On the present stage of knowledge it might be considered to establish a reference interval for dialysis patients. It appears that the fructosamine estimation may then be successfully applied also to dialysis patients. Although dialysis resulted in hemoconcentration, the fructosamine concentration remained virtually unchanged. Referencing both values before and after dialysis to protein or albumin improved the correlation, but substantial differences were introduced as well. However, none of several parameters measured in parallel interfered to a degree which might explain such differences. In order to find a reasonable explanation for these findings further experiments are necessary.
