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.
Spectral Absorb. Curve, Oxyhemoglobin, Carboxyhemoglobin, Carbon-Monoxide
Clinical Toxicology
This device is a spectral absorbance curve measurement system used to distinguish and quantify oxyhemoglobin and carboxyhemoglobin in blood specimens, supporting the diagnosis of carbon monoxide poisoning by identifying the characteristic shift in hemoglobin absorbance spectra caused by CO binding. It is classified as FDA Class 1, the lowest risk tier, requiring only general controls with no premarket submission. The product code is JKS, regulated under 21 CFR 862.3220, within the Clinical Toxicology 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.
