K925274 is an FDA 510(k) clearance for the AUTOCOMP(TM) SOFTWARE AND CALIBRITE(TM) BEADS. 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 September 30, 1994 after a review of 711 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Hematology submissions.
