K771378 is an FDA 510(k) clearance for the NEO TSH-RIA KIT. Classified as Radioimmunoassay, Thyroid-stimulating Hormone (product code JLW), Class II - Special Controls.

Submitted by Nuclear Medical Systems, Inc. (Mchenry, US). The FDA issued a Cleared decision on October 18, 1977 after a review of 90 days - within the typical 510(k) review window.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1690 - 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.
