When the FreeStyle LibreLink app* displays a Check Blood Glucose symbol, a fingerstick is required for treatment decisions. Fingersticks are also required 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. FreeStyle Libre 14 day readers all have a built-in blood glucose meter.
*The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check our compatibility guide for more information about device compatibility before using the app. Use of the FreeStyle LibreLink app requires registration with LibreView.
