A blood glucose test measures the amount of glucose in your blood. Glucose, a type of simple sugar, is your body’s main source of energy. Your body converts the carbohydrates you eat into glucose.
Glucose testing is primarily done to check for type 1 diabetes, type 2 diabetes, and gestational diabetes.
For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting. Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating.
