Note that FreeStyle LibreLink and Readers do not share data with each other. For complete information on a device, scan your Sensor every 8 hours with that device; otherwise, your reports will not include all your data. You can upload and view data from all of your devices on LibreView.com. APP INFORMATION FreeStyle LibreLink is intended for measuring glucose levels in people with diabetes when used with a Sensor. For more information on how to use FreeStyle LibreLink, refer to the User’s Manual, which can be accessed through the app. If you require a printed User’s Manual, contact Abbott Diabetes Care Customer Support. Learn more about FreeStyle LibreLink at http://FreeStyleLibre.us. [1] If you are using the FreeStyle LibreLink app, you must also have access to a blood glucose monitoring system as the App does not provide one. Fingersticks are required for treatment decisions when you see the Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.
