K050423 is an FDA 510(k) clearance for the OMNI MODULAR, OMNI C AND OMNI S ANALYZER (PH ELECTRODE). Classified as Electrode Measurement, Blood-gases (pco2, Po2) And Blood Ph (product code CHL), Class II - Special Controls.

Submitted by Roche Diagnostics (Indianapolis, US). The FDA issued a Cleared decision on April 22, 2005 after a review of 63 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1120 - 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.
