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.

The Powered Liquid Crystal Thermographic System for Adjunctive Use is an imaging device that uses liquid crystal technology with an electrical power source to map skin surface temperature patterns, intended for use alongside other diagnostic methods in assessing conditions such as breast pathology. It is classified as FDA Class 3, the highest risk level, requiring Premarket Approval (PMA) before marketing. The product code is KXZ, regulated under 21 CFR 884.2982, in the Obstetrics/Gynecology medical specialty. No special flags apply to this 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.
