Fasting Blood Glucose

The Fasting Blood Glucose test measures the level of sugar in your blood after you have not eaten for several hours. Fasting gives a clear baseline reading without the influence of a recent meal.

This test is widely used to screen for diabetes and prediabetes and to monitor blood sugar control over time. A raised result may indicate that the body is not managing glucose well, and it is usually confirmed with repeat or additional testing such as HbA1c.
