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.
Kit, Serological, Negative Control
Clinical Chemistry
The Serological Negative Control Kit is a reference reagent used in clinical and diagnostic laboratories as a negative control specimen during serological testing, verifying that the assay does not produce false-positive results in the absence of the target analyte. Classified as a Class 1 device under 21 CFR 862.1660 within the Clinical Chemistry specialty, it is subject only to general controls and is generally exempt from 510(k) premarket notification. It carries no implant or life-sustaining flags.

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.
