K821983 is an FDA 510(k) clearance for the TITAN GEL LDH ISOENZYME KIT. Classified as Chromatographic Separation, Lactate Dehydrogenase Isoenzymes (product code CEX), Class II - Special Controls.

Submitted by Helena Laboratories (Walker, US). The FDA issued a Cleared decision on December 22, 1982 after a review of 169 days - an extended review 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
