K040290 is an FDA 510(k) clearance for the DIASORIN LIAISON CMV IGM/IGG. Classified as Enzyme Linked Immunoabsorbent Assay, Cytomegalovirus (product code LFZ), Class II - Special Controls.

Submitted by Diasorin S.P.A (Stillwater, US). The FDA issued a Cleared decision on June 1, 2005 after a review of 481 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3175 - 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.
