what is fasting glucose range

Fasting glucose levels are measured after not eating or drinking (except water) for at least 8 hours. The ranges are typically categorized as follows:

• Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
• Prediabetes: 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 help diagnose prediabetes or diabetes and assess overall blood sugar control. Always consult your healthcare provider for personalized interpretation and advice.
