K970761 is an FDA 510(k) clearance for the LIMITED HUMAN LYME IGG WESTERN BLOT KIT (CAMBRIDGE DIAGNOSTICS IRELAND). Classified as Reagent, Borrelia Serological Reagent (product code LSR), Class II - Special Controls.

Submitted by Cambridge Diagnostics Ireland, Ltd. (Galway, IE). The FDA issued a Cleared decision on April 9, 1998 after a review of 402 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3830 - 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.
