K933461 is an FDA 510(k) clearance for the BOEHRINGER MANNHEIM BICARBONATE ASSAY. Classified as Enzymatic, Carbon-dioxide (product code KHS), Class II - Special Controls.

Submitted by Boehringer Mannheim Corp. (Indianapolis, US). The FDA issued a Cleared decision on December 5, 1994 after a review of 507 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1160 - 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.
