what fasting blood sugar is diabetes

A fasting blood sugar level is used to diagnose diabetes. According to the American Diabetes Association (ADA), the following ranges apply:

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

If your fasting blood sugar is 126 mg/dL or higher, it indicates diabetes. It's important to confirm this with a healthcare professional, as additional tests like the A1C test or an oral glucose tolerance test may be required for a definitive diagnosis.
