K823578 is an FDA 510(k) clearance for the COBAS STANDARDS FOR CALCIUM-IN-ORGANIC. Classified as Thymolphthalein Monophosphate, Alkaline Phosphatase Or Isoenzymes (product code CIO), Class II - Special Controls.

Submitted by Hoffmann-La Roche, Inc. (Mchenry, US). The FDA issued a Cleared decision on January 7, 1983 after a review of 32 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1050 - 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.
