An international expert committee composed of appointed representatives of the American Diabetes Association, the European Association for the Study of Diabetes, and others recommended HbA1c assay for diagnosing diabetes mellitus. [3] The committee recommended that an HbA1c level of 6.5% or higher be considered indicative of diabetes, with diagnostic confirmation being provided through repeat testing (unless clinical symptoms are present and the glucose level is >200 mg/dL). Glucose measurement should remain the choice for diagnosing pregnant women or be used if HbA1c assay is unavailable. The committee cited the following advantages of HbA1c testing over glucose measurement:

  • Captures long-term glucose exposure

  • Has less biologic variability

  • Does not require fasting or timed samples

  • Is currently used to guide management decisions
