K861750 is an FDA 510(k) clearance for the CK/LD BUFFER (CAT. NO. 5808). Classified as Electrophoretic, Lactate Dehydrogenase Isoenzymes (product code CFE), Class II - Special Controls.

Submitted by Helena Laboratories (Beaumont, US). The FDA issued a Cleared decision on May 29, 1986 after a review of 23 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.
