(a) 
         This part sets forth the classification of immunology and microbiology devices intended for human use that are in commercial distribution.
     
    
        
        (b) 
         The indentification of a device in a regulation in this part is not a precise description of every device that is, or will be, subject to the regulation. A manufacturer who submits a premarket notification submission for a device under  part 807 may not show merely that the device is accurately described by the section title and identification provisions of a regulation in this part, but shall state why the device is substantially equivalent to other devices, as required by  § 807.87.
     
    
        
        (c) 
         To avoid duplicative listings, an immunology and microbiology device that has two or more types of uses (e.g., used both as a diagnostic device and as a microbiology device) is listed only in one subpart.
     
    
        
        (d) 
         References in this part to regulatory sections of the Code of Federal Regulations are to chapter I of title 21, unless otherwise noted.
