Device Classification

Product Code QBJ Integrated Continuous Glucose Monitoring System, Factory Calibrated
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1355
Definition An Integrated Continuous Glucose Monitoring System (icgm) Is Intended To Automatically Measure Glucose In Bodily Fluids Continuously Or Frequently For A Specified Period Of Time. Icgm Systems Are Designed To Reliably And Securely Transmit Glucose Measurement Data To Digitally Connected Devices, Including Automated Insulin Dosing Systems, And Are Intended To Be Used Alone Or In Conjunction With These Digitally Connected Medical Devices For The Purpose Of Managing A Disease Or Condition Related To Glycemic Control.
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.
