K841641 is an FDA 510(k) clearance for the CORNING MAGIC CORTISOL RADIOIMMUNO. Classified as Radioimmunoassay, Cortisol (product code CGR), Class II - Special Controls.

Submitted by Corning Medical & Scientific (Mchenry, US). The FDA issued a Cleared decision on September 4, 1984 after a review of 137 days - within the typical 510(k) review window.

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

Device Classification

Product Code CGR Radioimmunoassay, Cortisol
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1205
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Chemistry devices follow this clearance model.
