K210596 is an FDA 510(k) clearance for the ARCHITECT Toxo IgG. Classified as Enzyme Linked Immunoabsorbent Assay, Toxoplasma Gondii (product code LGD), Class II - Special Controls.

Submitted by Abbott Laboratories (Abbott Park, US). The FDA issued a Cleared decision on May 19, 2022 after a review of 444 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3780 - the FDA microbiology 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 Microbiology submissions.

Device Classification

Product Code LGD Enzyme Linked Immunoabsorbent Assay, Toxoplasma Gondii
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.3780
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 Microbiology devices follow this clearance model.
