K923503 is an FDA 510(k) clearance for the URIC ACID ENZYMATIC COLORIMERIC KIT. Classified as Acid, Uric, Uricase (colorimetric) (product code KNK), Class I - General Controls.

Submitted by Randox Laboratories, Ltd. (Antrim, N. Ireland, IR). The FDA issued a Cleared decision on July 22, 1993 after a review of 372 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1775 - 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. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
