K771856 is an FDA 510(k) clearance for the DIR. QUANT. COLOR. DETERM. SERUM CREAT.. Classified as Alkaline Picrate, Colorimetry, Creatinine (product code CGX), Class II - Special Controls.

Submitted by Stanbio Laboratory (Mchenry, US). The FDA issued a Cleared decision on November 3, 1977 after a review of 35 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1225 - 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.
