what is the reference range for fasting blood glucose

The reference range for fasting blood glucose levels is as follows:

• Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
• Prediabetes (Impaired Fasting Glucose): 100–125 mg/dL (5.6–6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

These ranges are used to assess blood sugar control and diagnose conditions like prediabetes and diabetes. Always consult with a healthcare provider for personalized interpretation of your results.
