K243979 is an FDA 510(k) clearance for the Aptiva APS IgA Reagent. Classified as System,test,antibodies,b2 - Glycoprotein I (b2 - Gpi) (product code MSV), Class II - Special Controls.

Submitted by Inova Diagnostics, Inc. (San Diego, US). The FDA issued a Cleared decision on February 6, 2026 after a review of 410 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.

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.
