[Fructosamine reference ranges for pregnant patients and children determined using an improved NBT method].

Abstract

Reference values for fructosamine in pregnancy show a decrease with progressing pregnancy, which can be explained by pregnancy-associated hemodilution. A normalization to 7.0 g/dl total protein leads to values independent of gestational age. For children and adolescents age-dependency of the reference range is abolished if values are related to total protein. More plausible values are obtained in longitudinal profiles if fluctuations of protein concentration are taken into account.
