K841703 is an FDA 510(k) clearance for the TDX REA LDH. Classified as Nad Reduction/nadh Oxidation, Lactate Dehydrogenase (product code CFJ), Class II - Special Controls.

Submitted by Abbott Laboratories (Abbott Park, US). The FDA issued a Cleared decision on June 8, 1984 after a review of 46 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1440 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
