What is the Fasting Blood Sugar Test (Glucose)?
A fasting blood sugar test calculates the quantity of sugar (glucose) in the blood. It is a simple, safe, and widely used method of diagnosing prediabetes, diabetes, or gestational diabetes.
A health professional will prick your finger or insert a needle into a vein in your arm to draw the blood. For 8–12 hours before the test, don't drink or eat anything (except water). In most cases, doctors instruct patients to measure their fasting blood sugar instantly after waking up and before consuming any food or drink.
