NRSClass II21 CFR 864.8625510(k) exempt1 decision since 20041 recall

FDA lists NRS as exempt from 510(k): a device of this type needs no clearance unless one of the limits in 21 CFR 864.9 applies, such as a new intended use or a different fundamental technology. 1 FDA decision since 2004. 1 recall names this code; it is not Class I.

The Epithelial Cell Control Kit contains two levels of fixed cells that are stained with a fluorescence marker and are used to verify sample processing and cell analysis of circulating tumor cells. This device is used as an assay quality control to ensure that sample detection and identification systems are able to detect circulating epithelial tumor cells.
