K861122 is an FDA 510(k) clearance for the THE GOLDEN QUAD TEST (TOXO). Classified as Antisera, If, Toxoplasma Gondii (product code LJK), Class II - Special Controls.

Submitted by Microbiological Research Corp. (Bountiful, US). The FDA issued a Cleared decision on February 2, 1987 after a review of 314 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Microbiology review framework, consistent with the majority of Class II 510(k) 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 Microbiology devices follow this clearance model.
