K233655 is an FDA 510(k) clearance for the Lingo Glucose System. Classified as Integrated Continuous Glucose Monitor For Non-intensive Glucose Monitoring, Over-the-counter (product code SAF), Class II - Special Controls.

Submitted by Abbott (Alameda, US). The FDA issued a Cleared decision on May 29, 2024 after a review of 197 days - an extended review cycle.

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. Standard predicate reliance. 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 SAF Integrated Continuous Glucose Monitor For Non-intensive Glucose Monitoring, Over-the-counter
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1355
Definition An Integrated Continuous Glucose Monitoring System (icgm) For Non-intensive Glucose Monitoring Is Intended To Automatically Measure Glucose In Bodily Fluids Continuously Or Frequently For A Specified Period Of Time To Detect Euglycemic And Dysglycemic Glucose Levels In Persons Who Are Not On Insulin And Do Not Have A Significant Risk Of Problematic Hypoglycemia. Icgm Systems For Non-intensive Glucose Monitoring Are Designed To Reliably And Securely Transmit Glucose Measurement Data To Digitally Connected Devices, Excluding Devices Intended To Control The Delivery Of Insulin, And Are Intended To Be Used Alone Or In Conjunction With These Digitally Connected Medical Devices. Device Output Should Not Be Used To Make Treatment Decisions Without Consulting With A Qualified Healthcare Professional.
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.
