FreeStyle Libre 3 Sensor

About this item The FreeStyle Libre 3 Sensor is Abbott’s most advanced CGM sensor, delivering automatic real-time glucose readings directly to your smartphone every minute — with no scanning required. Its small, slim design makes it the smallest CGM sensor available from Abbott, offering improved comfort and discretion compared to previous Libre generations. The sensor continuously measures glucose in the interstitial fluid and sends updates via Bluetooth to the FreeStyle Libre 3 smartphone app. Users can view current glucose levels, trend arrows, and up to 14 days of continuous glucose history, helping them make more informed decisions about insulin, food, and daily activity. Customizable high, low, and urgent-low glucose alerts help notify you of important changes, even when you’re sleeping or active. Important: Always follow the manufacturer’s instructions for insertion and usage. If your symptoms do not match the displayed glucose reading, confirm using a blood glucose meter before making treatment decisions.
