K222610 is an FDA 510(k) clearance for the Elecsys Anti-Tg. Classified as System, Test, Thyroid Autoantibody (product code JZO), Class II - Special Controls.

Submitted by Roche Diagnostics (Indianapolis, US). The FDA issued a Cleared decision on September 15, 2023 after a review of 382 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5870 - the FDA immunology device 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 Immunology review framework, consistent with the majority of Class II 510(k) submissions.
