There’s no need to use a separate glucose meter for routine testing.* The app allows you to get glucose results as often as you like by simply scanning your FreeStyle Libre sensor with your phone.
However, a finger prick test using a blood glucose meter is required in the following situations:
- When you see the “Check Blood Glucose” symbol, you must check your blood glucose with a blood glucose meter before making any treatment decisions
- When your glucose is changing quickly
- If you get a “Low Glucose” or “Glucose Going Low” message
- If you do not see a Current Glucose number or Glucose Trend Arrow
- If you have symptoms that do not match the Sensor glucose reading or think that your reading may be inaccurate. If you have symptoms that do not match your glucose readings, consult your healthcare professional.
* The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the FreeStyle LibreLink app or when symptoms do not match the app readings. The FreeStyle Libre sensor communicates with the FreeStyle Libre reader that started it or the FreeStyle LibreLink app that started it. A sensor started by the FreeStyle Libre reader will also communicate with the FreeStyle LibreLink app. The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check the website for more information about device compatibility before using the app. Use of FreeStyle LibreLink requires registration with LibreView.
