K242505 is an FDA 510(k) clearance for the Elecsys Cortisol III. Classified as Fluorometric, Cortisol (product code JFT), Class II - Special Controls.

Submitted by Roche Diagnostics (Indianapolis, US). The FDA issued a Cleared decision on July 17, 2025 after a review of 329 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1205 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
