Basis of the Test
A fasting blood sugar (FBS) test is used to measure the amount of glucose (sugar) present in your blood after fasting for a whole night or for 8 hours. Glucose is the primary energy source for the body’s cells and the only energy source for the brain and nervous system. A steady supply must be available for use, and a relatively constant level of glucose must be maintained in the blood.
