Random Blood Sugar

The postprandial blood sugar test measures the amount of glucose in your blood about 2 hours after eating. Typically, blood sugar starts to rise 10-15 minutes after a meal and peaks around an hour later. Insulin, a hormone made by the pancreas, helps move sugar from your blood into your cells for energy. This test helps doctors understand how your body processes sugar after eating. If your blood sugar stays too high or too low, your doctor might recommend this test. For people without diabetes, blood sugar levels usually return to normal within 2 hours after eating.
