K961566 is an FDA 510(k) clearance for the BIOCIRCUITS IOS TSH TEST CARTRIDGES/THYROID CONTROLS. Classified as Radioimmunoassay, Thyroid-stimulating Hormone (product code JLW), Class II - Special Controls.

Submitted by Biocircuits Corp. (Sunnyvale, US). The FDA issued a Cleared decision on November 18, 1996 after a review of 209 days - an extended review cycle.

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.
