The above reference ranges reflect new criteria for the diagnosis of diabetes mellitus established by the American Diabetes Association ((Diabetes Care, Volume 34, Supplement 1, January 2011). All recommendations of the ADA are based upon plasma or serum levels). The diagnosis of diabetes mellitus should NOT be made until one of these abnormalities has been confirmed on a subsequent day. Impaired glucose tolerance/impaired fasting glucose implies an increased risk of future diabetes.
Reference ranges for random glucose adopted from Soldin et al. Pediatric Reference Intervals, 6th edition, 2007 and from Pediatric Reference Range Guidelines for Synchron Systems from Beckman Coulter.
