3.9-5.5 mmol/L (70-100 mg/dL)CPG
[mmol/L] × 18 = [mg/dL]
Interpretation of results
↑ Abnormal fasting plasma glucose (FPG; 5.6-6.9 mmol/L), impaired glucose tolerance (7.8-11.1 mmol/L at 120 minutes on 75-g oral glucose tolerance test [OGTT]); diabetes (fasting glucose ≥7.0 mmol/L [repeat], >11.1 mmol/L at 120 minutes on 75-g OGTT) or HBA1c ≥6.5%
Prediabetes: FPG 6.1-6.9 mmol/L and/or HBA1c 6.0-6.4%
↓ Hypoglycemia (eg, insulinoma, reactive hypoglycemia)
