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.
Immunochemical, Bence-Jones Protein
Immunology
This device is an immunochemical test system used to detect Bence-Jones protein (free immunoglobulin light chains) in urine, a finding associated with plasma cell dyscrasias such as multiple myeloma and Waldenstrom macroglobulinemia, where abnormal light chains are filtered into the urine. It is classified as FDA Class 2 and requires 510(k) premarket notification, falling under the Immunology medical specialty, regulated under 21 CFR 866.5150. This device is eligible for third-party 510(k) review.

4 matchesWhat 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.
