The American Diabetes Association (ADA) revised clinical practice recommendations for diabetes diagnosis promote hemoglobin A1c (A1c) as a faster, easier diagnostic test that could help reduce the number of undiagnosed patients and better identify patients with prediabetes.
The A1c test, which measures average blood glucose levels for a period of up to 3 months, was previously used only to evaluate diabetic control with time.
The new recommendations are published December 29 in the January supplement of Diabetes Care.
- An A1c level of approximately 5% indicates the absence of diabetes
- An A1c score of 5.7% to 6.4% indicates prediabetes,
- An A1c level of 6.5% or higher indicates the presence of diabetes.
For optimal diabetic control, the recommended ADA target for most people with diabetes is an A1c level no greater than 7%. It is hoped that achieving this target would help prevent serious diabetes-related complications including nephropathy, neuropathy, retinopathy, and gum disease.
