The Postprandial Blood Sugar Test can help detect prediabetes, type 1 diabetes, type 2 diabetes, gestational diabetes, and other types of diabetes. It is a blood glucose test that helps determine your blood sugar levels two hours after a meal. If your postprandial blood sugars are above 140-200 mg/dL, it indicates that you may have diabetes mellitus. This test is also recommended for people with diabetes to monitor their sugar control. Regular monitoring and well-controlled postprandial blood sugar can help minimise the risk of cardiovascular and other health complications due to diabetes. The test can be taken by people of all age groups or as recommended by your doctor.
