Formula: ADA ADAG Formula: eAG (mg/dL) = 28.7 × HbA1c (%) - 46.7. ADA Tiers: Normal (<5.7%), Prediabetes (5.7%-6.4%), Diabetes (≥6.5%), Diabetic Target (<7.0%).

In-Depth Guide & Mathematical Methodology

🩸 ADA Clinical Glycemic Diagnostic Thresholds

Normal: HbA1c < 5.7% (eAG < 117 mg/dL).

Prediabetes: HbA1c 5.7% to 6.4% (eAG 117 to 137 mg/dL).

Diabetes Diagnostic Threshold: HbA1c ≥ 6.5% (eAG ≥ 140 mg/dL).

ADA Target for Diabetic Adults: HbA1c < 7.0% (eAG < 154 mg/dL).
