Measures your blood sugar level after 10–12 hours of fasting to screen for prediabetes and diabetes.
Also known as: Fasting Blood Sugar (FBS), Fasting Blood Glucose, Fasting Plasma Glucose (FPG)
The Blood Glucose Fasting (FBS) test measures the amount of glucose (sugar) in your blood after fasting for 10–12 hours. It is one of the most commonly recommended tests to screen for prediabetes and type 2 diabetes, and to monitor blood sugar control in people with diabetes.
