Do I need to bring an extra blood glucose meter?
You no longer need to carry a separate blood glucose meter for daily blood glucose testing10. Simply scan your FreeStyle Libre sensor with your phone to get your blood sugar level anytime, anywhere via the app.
However, when blood glucose levels change rapidly (at which point the glucose concentration in the interstitial fluid may not accurately reflect the glucose concentration in the blood), when the sensor indicates hypoglycemia or is about to occur, or when the symptoms do not match the sensor readings, a finger prick blood test with a blood glucose meter is still necessary.
