Product Code: CGR FDA class 2

Radioimmunoassay, Cortisol

Clinical Chemistry

View full classification →

The Radioimmunoassay, Cortisol test system (product code CGR) is an in-vitro diagnostic device used in clinical chemistry to measure cortisol levels in serum, plasma, or urine using a radioimmunoassay method, aiding in the diagnosis of adrenal disorders such as Cushing's syndrome and Addison's disease. It is classified as FDA Class 2, indicating moderate risk, and requires a 510(k) premarket notification. It falls under regulation 21 CFR 862.1205 in the Clinical Chemistry medical specialty. This device is eligible for third-party review under the FDA's accredited persons program.

What 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.
