[Docket No. FDA–2012–N–0165] 

Medical Devices; Immunology and 

Microbiology Devices; Classification of 

Norovirus Serological Reagents 

AGENCY: Food and Drug Administration, 

HHS. 

ACTION: Final rule. 

SUMMARY: 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. 

DATES: Effective Date: April 9, 2012. The 

classification was effective February 23, 

2011.
