what is the fasting blood glucose level

Fasting blood glucose level refers to the amount of glucose in your blood after not eating or drinking (except water) for at least 8 hours. It is a common test used to diagnose prediabetes and diabetes. Here are the standard ranges:

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

Fasting blood glucose is an important indicator of your metabolic health and is often used alongside other tests like the A1C test to assess diabetes risk.
