Overview
Abbott's FreeStyle Libre system is the world's most widely adopted continuous glucose monitoring platform, enabling people with diabetes to check their glucose level by scanning a small, round sensor worn on the back of the upper arm. The FreeStyle Libre 3 and Libre 3 Plus — the latest generations — are the smallest, thinnest CGM sensors available, providing continuous real-time glucose readings every minute sent automatically to a compatible smartphone without the need to scan. The system measures glucose via a tiny filament inserted just beneath the skin and provides 14 days of continuous monitoring per sensor. FreeStyle Libre is used by over 6 million people across 60+ countries, making it the highest-volume CGM system globally by user count. The system is used by people with Type 1 and Type 2 diabetes, gestational diabetes, and increasingly by healthcare professionals managing inpatient hyperglycemia through the LibreLink Up app, which allows caregivers and family members to view a user's glucose data remotely in real time. Abbott's competitive positioning is built on accessibility and scale: FreeStyle Libre is priced more accessibly than competitors in many markets and is covered broadly by national health systems in Europe, driving extraordinary penetration in countries including Germany, France, and the United Kingdom. The LibreView cloud platform aggregates data across patient populations for clinical analysis, and Abbott continues expanding into non-diabetic metabolic health monitoring with successive sensor generations.
