RT Journal Article SR Electronic T1 Total glycosylated haemoglobin (HbA1) levels in diabetic children. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 434 OP 437 DO 10.1136/adc.57.6.434 VO 57 IS 6 A1 N P Mann A1 D I Johnston YR 1982 UL http://adc.bmj.com/content/57/6/434.abstract AB Total glycosylated haemoglobin (HbA1) levels from capillary blood were studied retrospectively during a 1-year period in 148 diabetic children aged between 1.9 and 16.8 years. The clinic range for HbA1 was 6.7 to 22.2% and the results were normally distributed (mean +/- SD 13.2 +/- 2.8%). The normal range in non-diabetics using this method is 4.9 to 8.0%. Results from children who had had diabetes for more than 5 years were higher than those from children with diabetes of 2 to 5 years' duration. Girls had higher average values during the 1-year period than boys. HbA1 measurement serves to identify the deficiencies of current diabetic treatment regimens. It also has more immediate practical benefits in focusing attention on children whose control is deteriorating.
