K221550 is an FDA 510(k) clearance for the Evidence MultiSTAT DOA Urine MultiPlex. Classified as Enzyme Immunoassay, Opiates (product code DJG), Class II - Special Controls.

Submitted by Randox Laboratories Limited (Crumlin, GB). The FDA issued a Cleared decision on October 5, 2023 after a review of 492 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Toxicology FDA review panel, regulated under 21 CFR 862.3650 - the FDA toxicology 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 Toxicology submissions.
