K201228 is an FDA 510(k) clearance for the Psychemedics Homogeneous Enzyme Immunoassay for Cocaine in Hair. Classified as Enzyme Immunoassay, Cocaine (product code JXO), Class II - Special Controls.

Submitted by Psychemedics Corporation (Culver City, US). The FDA issued a Cleared decision on June 25, 2021 after a review of 414 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Toxicology FDA review panel, regulated under 21 CFR 862.3250 - 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.
