what does high glucose mean in a blood test

High glucose levels in a blood test indicate that your blood sugar is elevated, which could be a sign of prediabetes or diabetes. Here’s what it means:

• Normal Range: Fasting blood glucose levels below 100 mg/dL.
• Prediabetes: Fasting blood glucose levels between 100–125 mg/dL.
• Diabetes: Fasting blood glucose levels of 126 mg/dL or higher on two separate tests.

High glucose levels can result from:

• Insulin Resistance: Your body isn’t using insulin effectively.
• Lack of Insulin: Your pancreas isn’t producing enough insulin.
• Diet and Lifestyle: High carbohydrate intake or lack of physical activity.

If your blood test shows high glucose, consult your healthcare provider for further evaluation and management.
