Device Classification

Product Code OZE Influenza A And Influenza B Multiplex Nucleic Acid Assay
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.3980
Definition An Influenza A And Influenza B Multiplex Nucleic Acid Assay Is A Multiplex In Vitro Diagnostic Test For The Simultaneous Qualitative Detection And Discrimination Of Influenza A And Influenza B Nucleic Acids Isolated And Purified From Human Respiratory Specimens Obtained From Individuals Exhibiting Signs And Symptoms Of Respiratory Tract Infections Or Viral Culture. The Detection And Discrimination Of Influenza A And B Nucleic Acids From Symptomatic Patients Aid In The Diagnosis Of Human Respiratory Tract Influenza Viral Infections If Used In Conjunction With Other Clinical And Laboratory Findings.
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.
