K933694 is an FDA 510(k) clearance for the SIGMA GLUCOSE REAGENT. Classified as Glucose Oxidase, Glucose (product code CGA), Class II - Special Controls.

Submitted by Sigma Chemical Co. (St. Louis, US). The FDA issued a Cleared decision on November 4, 1994 after a review of 463 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1345 - 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Chemistry submissions.
