510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Dna-Probe, Agent, Listeria
Microbiology
The Listeria agent DNA probe is a microbiology in vitro diagnostic device that uses nucleic acid hybridization to detect Listeria species in clinical or environmental specimens, supporting rapid identification of this foodborne and opportunistic pathogen. It is classified as FDA Class I under 21 CFR 866.3355 within the Microbiology specialty, subject only to general controls. The product code is MCG and the device is not GMP-exempt. It is not implanted and does not sustain life.
No 510(k) clearances found for "MCG". Try a different K-number, product code, or device name.
What is a Predicate Device?
A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
