Checking your Blood Sugar
Use a continuous glucose monitor (CGM) or a blood sugar meter (also known as a glucometer) to test your blood sugar. A blood sugar meter gauges the level of sugar in a tiny amount of blood, typically from the tip of your finger. Every few minutes, a CGM measures your blood sugar using a sensor placed under the skin. To ensure the accuracy of your CGM readings, you must still test your blood sugar on a daily basis.
