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.
Fluorometer, For Clinical Use
Clinical Chemistry
Clinical Fluorometer is a laboratory instrument used in clinical chemistry that measures the fluorescence emitted by chemical compounds in a sample when excited by light of a specific wavelength, enabling quantitative analysis of fluorescent analytes such as drugs, metabolites, and other biochemical substances in clinical specimens. It is classified as FDA Class 1, the lowest risk category, subject to general controls only, meaning it does not require premarket notification or approval. The product code is KHO, regulated under 21 CFR 862.2560, 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.
