Medically reviewed by Neesh Patel, MB DCH

Has your healthcare professional advised a fasting blood sugar (FBS) test? You may wonder what FBS testing is and why I should undertake a test for diabetes. So let’s discuss this test, including fasting blood sugar level, price, who should get this test, what happens during the test, and much more.

What is the FBS test?

FBS test means fasting blood sugar test, a quick, routine blood test to check for diabetes, prediabetes, or gestational diabetes (during pregnancy). Fasting blood glucose testing is another name for it. The FBS test is not only used to screen for diabetes and prediabetes. It also evaluates how well diabetes patients’ medications or dietary modifications work.

What does a Fasting Blood Sugar (FBS) test measure?

A Fasting Blood Sugar (FBS) test measures your blood’s sugar (glucose) concentration. It determines whether the body can effectively use or store glucose.

Who Needs to Get Their Fasting Blood Sugar (FBS) Checked?

If you are exhibiting any of the following diabetic symptoms, your doctor may recommend glucose testing:
  • Unreasonable weight loss
  • Distorted vision
  • Dry skin
  • Excessive thirst or hunger
  • Tiredness
  • Bruises that take a while to heal
  • Abnormally high infection rates
  • Frequent urinating
  • Tingling or numbing
The presence of risk factors of diabetes, such as the following, may also compel your doctor to include glucose testing in a panel of background health checks:-
  • Not exercising enough or at all
  • Being obese or overweight
  • Having a polycystic ovarian syndrome
  • Being detected with prediabetes – means blood sugar levels are elevated but not to the point of type 2 diabetes.
  • Having reached the age of 45 or more
  • Having diabetes in the family
  • Suffering from heart disease, hypertension, or high cholesterol
  • Being pregnant – To check for gestational diabetes, which harms both mother and baby.

What is the Normal FBS level?

The FBS test normal range is 70 to 100 mg/dl, and the normal fasting sugar level is less than 100 mg/dl.

What is FBS Test Price?

The FBS test cost can be anything between ₹50 and ₹70. It significantly depends on the city you reside and the lab of your choice.

What Can You Anticipate on the Day of the Test?

A healthcare provider inserts a clean needle into your vein. This is done to draw blood into a phial attached to the needle and labelled with your personal information. You may feel like a brief pinch during this process.

But before doing that, they clean the area inside your elbow and tie a band around your upper arm. This band helps the veins in your arm to fill with blood.

They remove the band and the needle once they collect enough blood for the test. Then they place a bandage on the area. After the test, they send the blood sample to a lab for testing.

When Will I Get the Test's Result?

You receive the FBS test results quickly, typically within a few hours or a day.
