K951100 is an FDA 510(k) clearance for the ORTHO-MUNE OK-COMBO CD3-FITC/CD19-PE (OKT3/OKB19A MONOLCLONAL ANTIBODY (MURINE). Classified as Counter, Differential Cell (product code GKZ), Class II - Special Controls.

Submitted by Ortho Diagnostic Systems, Inc. (Raritan, US). The FDA issued a Cleared decision on May 13, 1996 after a review of 430 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.
