Fasting Blood Sugar Test

What is It?

The fasting blood sugar (FBS) test measures the amount of sugar (glucose) in your blood after you’ve not eaten or had anything to drink (except water) for at least 8 hours. It helps your doctor understand how well your body is managing blood sugar levels.

Why is the Fasting Blood Sugar Test Important?

• It’s used to check for diabetes or pre-diabetes.

• It can monitor how well your blood sugar is being controlled if you already have diabetes.

• High blood sugar levels over time can lead to serious health problems, so this test is crucial for early detection and management.

How is the Test Done?

1. You’ll need to fast (not eat or drink anything except water) for 8-12 hours before the test.

2. A small blood sample is taken from a vein in your arm.

3. The sample is analyzed in a lab, and the doctor reviews the results.

What Do the Results Mean?

• Normal: Fasting blood sugar levels are usually between 70 and 99 mg/dL.

• Pre-diabetes: Levels between 100 and 125 mg/dL may indicate a risk for developing diabetes.

• Diabetes: If the level is 126 mg/dL or higher, it could mean you have diabetes.

What Should You Do Before the Test?

Don’t eat or drink anything except water for 8-12 hours before the test.

Try to schedule the test in the morning to make fasting easier.

Let your doctor know if you’re taking medications, as some may affect your blood sugar levels.

What Happens After the Test?

Your doctor will explain your blood sugar levels:

• If the results are high, they may recommend lifestyle changes, medication, or further tests to confirm diabetes.

• If the results are normal, it means your blood sugar is within a healthy range, but regular monitoring is still important.

In summary, the fasting blood sugar test helps detect early signs of diabetes or monitor your blood sugar levels to ensure they’re under control, making it a key tool in maintaining good health.
