2009 American Diabetes Association (ADA) Recommendations Regarding HbA1c Measurement

A1C

• Perform the A1C test at least two times a year in patients who are meeting treatment goals (and who have stable glycemic control).
• Perform the A1C test quarterly in patients whose therapy has changed or who are not meting glycemic goals.
• Use of point-of-care testing for A1C allow for timely decisions on therapy changes, when needed.

Glycemic Gloals in Adults

• Lowering A1C to below or around 7% has been shown to reduce microvascular and neuropathic complications of type 1 and type 2 diabetes.  Therefore, for microvascular disease prevention, the A1C goal for nonpregnant adults in general is <7%.
