K100943 is an FDA 510(k) clearance for the INVADER FACTOR II. Classified as Test, Factor Ii G20210a Mutations, Genomic Dna Pcr (product code NPR), Class II - Special Controls.

Submitted by Hologic, Inc. (Malborough, US). The FDA issued a Cleared decision on June 2, 2011 after a review of 422 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Pathology FDA review panel, regulated under 21 CFR 864.7280 - the FDA pathology 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 Pathology submissions.
