[Serum fructosamine in healthy and diabetic children and adolescents].

The determination of fructosamine in serum of healthy newborns, children and adolescents by a new colorimetric method leads to an age-dependent reference range. Correction of the values for total protein yields a median of the results, which is not dependent on age and the upper limit of the reference range is not significantly different from that of healthy adults; this does not hold true for referral to albumin. As the half-life time of glycated serum proteins is shorter (mean 20 days) than that of hemoglobin A1c, fructosamine can provide useful additional informations about the diabetic control of children and adolescents (medium-term record of blood glucose).
