| Level . | Glycemic criteria . | Description . |
|---|---|---|
| Hypoglycemia alert value (level 1) | ≤70 mg/dL (3.9 mmol/L) | Sufficiently low for treatment with fast-acting carbohydrate and dose adjustment of glucose-lowering therapy |
| Clinically significant hypoglycemia (level 2) | <54 mg/dL (3.0 mmol/L) | Sufficiently low to indicate serious, clinically important hypoglycemia |
| Severe hypoglycemia (level 3) | No specific glucose threshold | Hypoglycemia associated with severe cognitive impairment requiring external assistance for recovery |
