K890349 is an FDA 510(k) clearance for the SIMULTEST IMK FOR FACS ANALYZER OR FACSCAN. Classified as Counter, Differential Cell (product code GKZ), Class II - Special Controls.

Submitted by Becton Dickinson Immunocytometry Systems (San Jose, US). The FDA issued a Cleared decision on December 29, 1989 after a review of 339 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.5220 - the FDA hematology device 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. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Hematology review framework, consistent with the majority of Class II 510(k) submissions.
