K173833 is an FDA 510(k) clearance for the CRP Vario. Classified as Cardiac C-reactive Protein, Antigen, Antiserum, And Control (product code NQD), Class II - Special Controls.

Submitted by SENTINEL CH. SpA (Milano, IT). The FDA issued a Cleared decision on September 27, 2018 after a review of 283 days - an extended review cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 866.5270 - 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
