Testing your blood sugar level is one of the best ways to understand your diabetes and how different foods, medications, and activities affect your diabetes. Keeping track of your blood glucose can help you and your doctor make a plan to manage this condition. People use portable blood glucose meters, called glucometers, to check their blood sugarlevels. These work by analyzing a small amount of blood, usually from a fingertip. A lancet lightly pricks your skin to obtain the blood. Meters tell you your current blood sugar. But, since blood sugar levels change, you need to test levels often and record them.
