Fasting glucose measures the amount of sugar in your blood after an overnight fast. It's one of the simplest tests for screening diabetes and prediabetes. A fasting glucose below 100 mg/dL is normal, 100–125 mg/dL indicates prediabetes, and 126 mg/dL or above suggests diabetes. While simpler than A1c, it reflects only a single point in time.
Diabetes and blood-sugar testing identifies insulin resistance, pre-diabetes, and diabetes early — when lifestyle changes still have the highest impact.
Adults with risk factors for diabetes: family history, overweight/obesity, sedentary lifestyle, prior gestational diabetes, or signs like increased thirst, fatigue, or unexplained weight changes.
