Don't know if this addition to diagnostic criterion has been mentioned already ...
February 2010? The American Association of Clinical Endocrinologists (AACE) and the American
College of Endocrinology (ACE) have evaluated the role of A1c for the diagnosis of type 2 diabetes
(diabetes). The American Diabetes Association (ADA) 2010 Clinical Practice Recommendations
endorse the use of A1c of 6.5% or higher as the primary criterion for the diagnosis of diabetes.
The rationale for the use of A1c for diagnosis is based on data showing that retinopathy occurs in
individuals with an A1c ≥6.5% at approximately the same rate as in individuals who are diagnosed
based on the current fasting and post-challenge glucose criteria. A 10% risk for retinopathy has
historically served as the bench mark for diagnosing the presence of diabetes.
The use of A1c for the diagnosis of diabetes has several advantages. It does not require the patient
to be fasting, can be done at any time that a visit is scheduled, is simpler to perform than the 2 hr
oral glucose test, and is less dependent on the patient?s health status at the moment of the blood
draw. However, use of A1c ≥6.5% identifies approximately 20% fewer people with diabetes than do
existing criteria based on fasting plasma glucose and oral glucose tolerance tests.
