Medical devices; immunology and microbiology devices; classification of norovirus serological reagents. Final rule

The Food and Drug Administration (FDA) is classifying norovirus serological reagents into class II (special controls). The special control that will apply to these devices is the guidance document entitled ``Class II Special Controls Guidance Document: Norovirus Serological Reagents.' The Agency is classifying these devices into class II (special controls) because special controls, in addition to general controls, will provide a reasonable assurance of safety and effectiveness of these devices and there is sufficient information to establish special controls.
