Principles of Operation
The analyzer counts, sizes and classifies blood cells by the combination of flow cytometry methods: Laser Optical Scatter and Fluorescence, Focused Flow Impedance, and Absorption Spectrophotometry. The IRF is derived from the intensity of the fluorescence measured for the Reticulocyte parameters. The Cell-Dyn® 4000 System uses an Argon-ion laser as the optical light source. The Optical Bench detects light in the form of scatter from blood cell surfaces and internal structures, or fluorescent light from specially stained blood cells.
For the WBC parameters and NRBCs, whole blood is diluted with a reagent containing a red fluorescent dye. Data are simultaneously collected for four angles (0°, 7°, 90°, and 90ºD) of scatter and red fluorescence (FL3) as each cell passes through the laser beam. NRBCs, identified by fluorescence, are excluded automatically from the WBC count.

510(k) Notification
For the RBC and the PLT parameters, whole blood is diluted with a reagent that prepares the cells for measurement. The dilution is split and measured by both laser optical scatter (7° and 90°) and Focused Flow Impedance with Injection Metering.
For the hemoglobin parameters, whole blood is diluted with a cyanide free reagent and the hemoglobin is measured optically by absorbance (540nm).
For the reticulocyte parameters, an aliquot of the RBC/PLT dilution is diluted with a reagent containing a green fluorescent dye. Data are collected for scatter (7°) and green fluorescence (FL1) as each cell passes through the laser beam.
Similarities and Differences
The Cell-Dyn® 4000 System, Coulter® Counters (Model ZBI, S-Plus Series and STKS), Abbott Cell-Dyn® 3000 Series, and the Cell-Dyn® 4000 System with IRF are similar in that they use impedance for counting and sizing RBCs and PLTs. The Cell-Dyn 4000 System with IRF and the Sysmex™ NE series are similar in that they both use Focused Flow Impedance to count and size RBCs and PLTs. The Technicon H*1™ series and the Cell-Dyn® 4000 System with IRF are similar in that they both use Injection Metering to measure RBCs and PLTs optically. The Cell-Dyn® 4000 System with IRF is different in that it counts RBCs and PLTs by both the optical and impedance methods and compares the data as an internal quality check.
WBCs are counted and classified by the Cell-Dyn® 4000 System, Abbott Cell-Dyn® 3000 Series Systems and the Cell-Dyn® 4000 System with IRF in a very similar manner using four simultaneously collected angles of laser light scatter. They are different in that the Abbott Cell-Dyn® 3000 Series Systems use a helium neon laser, while the Cell-Dyn® 4000 System and the Cell-Dyn®4000 System with IRF use an Argon-ion laser that allows fluorescent data to be collected simultaneously with the optical scatter data. This change enables the Cell-Dyn 4000 System and the Cell-Dyn 4000 System with IRF to count and classify WBCs, NRBCs, and fragile (nonviable) WBCs. The Becton Dickinson FACScan™, the Cell-Dyn® 4000 System, and the Cell-Dyn 4000 System with IRF all use an Argon-ion laser. The FACScan is also capable of identifying NRBCs and nonviable WBCs. NRBCs are stained for enumeration by both the Cell-Dyn® 4000 System and the manual microscopic differential.
The Becton Dickinson FACScan™, the Sysmex™ R-3000, the Cell-Dyn® 4000 System, and the Cell-Dyn® 4000 System with IRF are similar in that they enumerate reticulocytes in EDTA-anticoagulated whole blood using optical laser scatter and fluorescence. They are different in that for the Becton Dickinson FACScan™, specimens are externally stained with Thiazol Orange an incubated for 90 minutes and then manually presented for measurement. For the Sysmex™ R-3000, specimens are automatically diluted and stained using Auromine Orange and then measured. The Cell-Dyn® 4000 System and the

Cell-Dyn® 4000 System with IRF are different in that they automatically dilute the specimen with a fast acting proprietary dye which requires no incubation prior to measurement.
Equivalency Data
The data complied to support the claim that the Cell-Dyn® 4000 System with IRF is substantially equivalent to the Abbott the Cell-Dyn® 4000 and Cell-Dyn® 3500 Systems includes accuracy, precision, linearity, and carryover. The data supports the claim that the Cell-Dyn® 4000 System with IRF is substantially equivalent to the Abbott Cell-Dyn® 4000 System and Abbott Cell-Dyn® 3500 System for the hemogram and automated WBC differential parameters and to the Abbott Cell-Dyn® 4000 System, the Becton Dickinson FACScan™, and the Sysmex™ R-3000 for the reticulocyte parameters. The accuracy, precision, and linearity data shows performance to manufacturer's specifications.
Conclusion
The Cell-Dyn® 4000 System with IRF shows an evolution of the technologies used on one or more of the currently available analyzers to count, size, and classify whole blood cells and their related parameters, and more specifically to the technologies used on the Cell-Dyn® 4000 System, Abbott Cell-Dyn® 3500 System, the Becton Dickinson FACScan™ and the Sysmex™ R-3000.
