what does fasting glucose mean

Fasting glucose refers to the level of glucose (sugar) in your blood after you have not eaten or consumed any caloric beverages for at least 8 hours. It is a common test used to diagnose prediabetes and diabetes. Here’s what the results typically indicate:

• Normal: Less than 100 mg/dL
• Prediabetes: 100 to 125 mg/dL
• Diabetes: 126 mg/dL or higher on two separate tests

Fasting glucose is an important measure because it provides a baseline of how well your body manages blood sugar without the influence of recent food intake.
