K121445 is an FDA 510(k) clearance for the TETRACHROME REAGENTS AND TETRACXP SYSTEM. Classified as Flow Cytometric Reagents And Accessories. (product code OYE), Class II - Special Controls.

Submitted by Beckman Coulter, Inc. (Miami, US). The FDA issued a Cleared decision on July 26, 2013 after a review of 437 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. As a Special 510(k), this submission covers a manufacturer modification to an existing cleared device rather than a new device introduction.

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.
