K102428 is an FDA 510(k) clearance for the WUNDER TEST. Classified as Enzyme Immunoassay, Cannabinoids (product code LDJ), Class II - Special Controls.

Submitted by Hien Helen Nguyen (San Jose, US). The FDA issued a Cleared decision on April 18, 2012 after a review of 601 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Toxicology FDA review panel, regulated under 21 CFR 862.3870 - 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.
