K981338 is an FDA 510(k) clearance for the LD-1. Classified as Differential Rate Kinetic Method, Lactate Dehydrogenase Isoenzymes (product code JGF), Class II - Special Controls.

Submitted by Abbott Laboratories (Irving, US). The FDA issued a Cleared decision on May 18, 1998 after a review of 35 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1445 - 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.
