Glucose readings without fingersticks - Rather than taking glucose readings from your blood, CGM sensor readings are taken from interstitial fluid, a thin layer of fluid that surrounds the tissue cells below your skin. As carbohydrates are digested, glucose enters your bloodstream before it is absorbed into the interstitial fluid.
