The Fasting Blood Sugar Test is a blood glucose test that helps determine blood sugar levels in your body after fasting for more than eight hours. It helps detect prediabetes, type 1 diabetes, type 2 diabetes, gestational diabetes, and other types of diabetes. Fasting blood sugar levels above 125 mg/dL, indicate a possibility of diabetes mellitus, and the patient must be evaluated by a doctor. Your fasting sugar readings may be high if you have prediabetes, diabetes or gestational diabetes. This test is beneficial for routine monitoring of blood sugar levels in people diagnosed with diabetes. Regular monitoring and well-controlled blood sugar can minimise the risk of severe complications due to diabetes. This test can be taken by people of all age groups and/or as recommended by your doctor.
