Glucose is the primary energy source for the body. Carbohydrates in the food are broken down into glucose, which is then absorbed into the bloodstream and transported to the cells for energy. Insulin, produced by the pancreas, regulates the blood glucose level in the body. A lack of insulin or its reduced effectiveness can result in high blood glucose levels.High blood glucose levels can be a sign of diabetes or prediabetes (a condition where a person has high blood glucose levels but not yet at a level that qualifies as diabetes). Early detection and treatment of diabetes are essential to prevent complications such as heart disease, kidney damage, and nerve damage. An FBS test, also known as glucose fasting test helps screen for prediabetes and diabetes and checks the effectiveness of medications or lifestyle changes for diagnosed people.Fasting for at least 8–12 hours is recommended before undergoing the FBS (Fasting Blood Sugar) test. Do not eat or drink anything other than water during the fasting period. It is also important to inform the doctor about any medicines being taken, as some may affect the blood glucose levels and need to be adjusted or temporarily discontinued before the test.FBS test result ranges may vary across the laboratories depending on the methodology and laboratory guidelines. Do not self-medicate. Always consult your doctor to understand your test results. The results will help them understand your condition, suggest lifestyle changes like diet and exercise, to decide if you need medication, and create a treatment plan.
Yes. To ensure accurate results, follow these key requirements before taking a Glucose Fasting and Postprandial (PP) test.
A blood sample is taken from a vein in the arm for the fasting glucose test. The postprandial (PP) sample is collected 2 hours after eating a meal.
After the fasting sample, you should eat your regular meal. The second blood sample will be collected exactly 2 hours after the meal.
8–12 hours fasting is required before the fasting blood sugar test. Only plain water is allowed during the fasting period.
Inform your doctor about diabetes medications or insulin, as they may affect the results.
Avoid alcohol and smoking before the test, as they may influence blood glucose levels.
You will be asked not to consume anything except water for 8 to 12 hours before the test. This fasting period is essential as it ensures that your blood sugar levels are at their most natural state, devoid of any food intake influences.
