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.
Fluorometric, Cortisol
Clinical Chemistry
Fluorometric Cortisol measurement is a clinical chemistry test system that uses fluorescence-based detection to quantify cortisol (hydrocortisone) levels in biological specimens, supporting the diagnosis of adrenal disorders such as Cushing's syndrome and Addison's disease. It is classified as FDA Class 2 (moderate risk), requiring 510(k) premarket notification and adherence to general and special controls. The product code is JFT, regulated under 21 CFR 862.1205, within the Clinical Chemistry medical specialty. This device is eligible for third-party 510(k) review.

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.
