K201761 is an FDA 510(k) clearance for the FreeStyle Libre 2 Flash Glucose Monitoring System (with FreeStyle Libre 2 App). Classified as Integrated Continuous Glucose Monitoring System, Factory Calibrated, Not For Use With Automated Insulin Delivery Systems (product code QLG), Class II - Special Controls.

Submitted by Abbott Diabetes Care, Inc. (Alameda, US). The FDA issued a Cleared decision on July 30, 2021 after a review of 396 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1355 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code QLG Integrated Continuous Glucose Monitoring System, Factory Calibrated, Not For Use With Automated Insulin Delivery Systems
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1355
Definition An Integrated Continuous Glucose Monitoring System For Replacement Of Finger Stick Blood Glucose Testing For Diabetes Treatment Decisions In Persons With Diabetes, Unless Otherwise Indicated. The System Automatically Measures Glucose In Bodily Fluids Continuously Or Frequently For A Specified Period Of Time. The System Is Also Designed To Reliably And Securely Transmit Glucose Measurement Data To Digitally Connected Devices And Are Intended To Be Used Alone Or In Conjunction With These Digitally Connected Devices Where The User Manually Controls Actions For Therapy Decisions. The System Is Not Intended To Be Used With Automated Insulin Dosing (aid) Systems.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Chemistry devices follow this clearance model.
