K903430 is an FDA 510(k) clearance for the LIQUICHEK CK/LD ISOENZYME CONTROL. Classified as Enzyme Controls (assayed And Unassayed) (product code JJT), Class I - General Controls.

Submitted by Bio-Rad (Hercules, US). The FDA issued a Cleared decision on August 23, 1990 after a review of 23 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1660 - 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.
