FreeStyle Libre 3 Continuous Glucose Monitoring System

The FreeStyle Libre 3 is a continuous glucose monitoring (CGM) system developed by Abbott Laboratories, a leading global healthcare company headquartered in the United States. This innovative device is designed to provide real-time, minute-by-minute glucose readings directly to a compatible smartphone, enabling individuals with diabetes to monitor their glucose levels more effectively. The sensor is notably compact, approximately the size of two stacked U.S. pennies, making it the world's smallest and thinnest CGM sensor available. It offers a 14-day wear period, during which it delivers continuous glucose data without the need for fingerstick calibrations. The FreeStyle Libre 3 system is manufactured in multiple countries, reflecting Abbott's global production capabilities. As of 2025, Abbott Laboratories continues to own and operate the FreeStyle Libre brand, maintaining its commitment to advancing diabetes care through innovative technologies.
