[Measure of glycosylated hemoglobin A1c: its value in the control of juvenile insulin-dependent diabetes (author's transl)].

HbA1c percentage was determined in 82 insulin-dependent juvenile diabetic patients. The concentration of HbA1c reflects the level of chronic hyperglycaemia during the preceding 4 to 8 weeks and appears to correlate closely with the commonly used methods for monitoring diabetic control. HbA1c measurement provides a reliable and objective test for periodic assessment of insulin-dependent juvenile diabetes. It may serve as a valuable tool for determining the level of metabolic control in each patient and measuring the effectiveness of various therapeutic regimens.
