| Hgb A1c | Reference Range: 4.3 – 5.6% 5.7 – 6.4% – Increased Risk of Developing Diabetes Mellitus ≥ 6.5% – Consistent with diagnosis of Diabetes Mellitus In the absence of hyperglycemia (i.e. plasma glucose > 200 mg/dL) or classic symptoms of hyperglycemia a repeat measurement of HbA1c should be performed on a separate sample to confirm the diagnosis.
