K112223 is an FDA 510(k) clearance for the EUROIMMUN ANTI-LKM-1 ELISA(LGG). Classified as Autoantibodies, Lkm-1 (liver/kidney Microsome, Type 1) (product code NBS), Class II - Special Controls.

Submitted by Euroimmun US (Morris Plains, US). The FDA issued a Cleared decision on September 11, 2012 after a review of 406 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5660 - 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Immunology submissions.

Device Classification

Product Code NBS Autoantibodies, Lkm-1 (liver/kidney Microsome, Type 1)
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.5660
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 Immunology devices follow this clearance model.
