Why do you need to take this test?

As part of a medical examination, FBS is important to take by everyone. This is to know the blood sugar level on the body of a person.

Diabetes is a condition that causes your blood glucose levels to rise. The amount of sugar in your blood is usually controlled by a hormone called insulin. However, if you have diabetes, your body either doesn’t make enough insulin or the insulin produced doesn’t work properly. This causes sugar to build up in your blood. Increased levels of blood sugar can lead to severe organ damage if left untreated (


We recommend you to take fasting before taking the test. This is to ensure that the blood test records an accurate measure of fasting blood sugar levels.


If you had a fasting blood glucose test, a level between 70 and 100 mg/dL (3.9 and 5.6 mmol/L) is considered normal (medlineplus).
