Device Classification

Product Code QVF Simple Point-of-care Device To Directly Detect Sars-cov-2 Viral Targets From Clinical Specimens In Near-patient Settings
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.3982
Definition A Simple Point-of-care Device To Detect Sars-cov-2 Viral Targets Directly From Clinical Specimens In Near-patient Settings Is An In Vitro Diagnostic Device For The Direct Detection Of Sars-cov-2 In Clinical Specimens And Is Intended As An Aid In The Diagnosis Of Sars-cov-2 Infections Covid-19). The Device Is Simple To Use And Does Not Involve Sample Manipulation, Transportation Of The Sample To Another Functional Area (e.g., A Central Laboratory Or Other Specialized Area), Or Measurement Of Reagents Or Analytes That Could Be Affected By Conditions Such As Sample Turbidity Or Cell Lysis. The Design And Procedures Of The Device Are Appropriate For Use By Healthcare Professionals In Near-patient Settings Outside A Centralized Laboratory
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 Microbiology devices follow this clearance model.
