Medical Devices; Immunology and Microbiology Devices; Classification of Cystic Fibrosis Transmembrane Conductance Regulator Gene Mutation Detection System

The Food and Drug Administration (FDA) is classifying the cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation detection systems into class II (special controls). The special control that will apply to the device is the guidance document entitled "Class II Special Controls Guidance Document: CFTR Gene Mutation Detection Systems." The agency is classifying the device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device.
