In 2008,an Expert Committee was convened to redefine the diagnosis of diabetes mellitus (in non-pregnant individuals) using glycated hemoglobin (HbAlc).The Committee Members were appointed from the American Diabetes Association (ADA),the European Association for the Study of Diabetes (EASD) and the Intational Diabetes Federation (IDF).The recommendations1 were published in the July issue of Diabetes Care with an accompanying editorial2 and were presented at the 2009 ADA 69th Scientific Sessions.In 2010,the ADA stated in its Standards of Medical Care in Diabetes 2010 that HbAlc,fasting plasma glucose or the 2-hour 75 g oral glucose tolerance test (OGTT) are appropriate for testing diabetes and assessing the risk of future diabetes, andthata confirmed HbA1c≥6.5％ is diagnosic for diabetes.
