What is the Glucose Fasting Test?
The Fasting Blood Sugar (FBS) test measures the amount of glucose in your blood after an overnight fast. It is the simplest and most affordable test to screen for diabetes and prediabetes.
Because India has one of the largest populations of people with diabetes in the world — and many do not know they have it — doctors recommend a fasting sugar test as part of every adult health checkup.
What it measures: The level of glucose (sugar) in your blood after 8–10 hours without food.

How to prepare for the Glucose Fasting Test
- 1Fast for 8–10 hours before the test — nothing to eat or drink except plain water.
- 2Do not drink tea, coffee, milk or juice in the morning before the sample.
- 3If you take diabetes medicines or insulin, ask your doctor whether to take them before or after the sample.

Glucose Fasting Test normal range
| Parameter | Typical reference range |
|---|---|
| Normal | 70–99 mg/dL |
| Prediabetes (impaired fasting glucose) | 100–125 mg/dL |
| Diabetes | 126 mg/dL or higherconfirmed on two separate tests |
Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A single high reading should be confirmed with a repeat test or an HbA1c test before a diagnosis of diabetes is made.
- Prediabetes can often be reversed with diet, exercise and weight loss — early detection really matters.
