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.
Colorimetric Method, Gamma-Glutamyl Transpeptidase
Clinical Chemistry
The Colorimetric Method, Gamma-Glutamyl Transpeptidase test is a clinical chemistry diagnostic reagent used to measure gamma-glutamyl transpeptidase (GGT) activity in serum by a colorimetric reaction, providing an enzymatic marker used in the evaluation of hepatic and biliary disease, as well as monitoring of alcohol use. This device is FDA Class 1, the lowest risk category, requiring only general controls and no premarket submission. It carries product code JPZ and is regulated under 21 CFR 862.1360, within the Clinical Chemistry medical specialty.

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.
