What does the medical abbreviation FBS mean?

FBS stands for "fasting blood sugar". It refers to the measurement of blood sugar levels after an overnight fast, typically lasting 8 to 12 hours. FBS is one of the most common blood tests used to diagnose and monitor diabetes. It is also used to assess overall blood sugar control in individuals with diabetes.

If an individual has not eaten for at least 8 hours prior to the blood test, the result is considered a fasting blood sugar level. During the fast, the body's glycogen stores are depleted, and the liver produces glucose to maintain normal blood sugar levels. Measuring FBS provides an accurate representation of the body's baseline blood glucose concentration and can help identify potential abnormalities or disturbances in blood sugar regulation.
