Consequently, since 2010 the ADA has included an HbA1c level of 6.5% or higher as a criterion for diabetes diagnosis, with confirmation from repeat testing (unless clinical symptoms are present and the glucose level is >200 mg/dL). A target HbA1c level of less than 8% is supported for older patients (>60 y). Levels below 6% are associated with increased mortality. [150]
