K792599 is an FDA 510(k) clearance for the TIPSEP-T4(RIA) T4 RADIOIMMUNOASSAY. Classified as Radioimmunoassay, Total Thyroxine (product code CDX), Class II - Special Controls.

Submitted by Nuclear Diagnostics, Inc. (Mchenry, US). The FDA issued a Cleared decision on January 16, 1980 after a review of 29 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1700 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
