Device Story

Automated hematology analyzer; processes whole blood, pre-diluted blood, or body fluids. Uses impedance, radio frequency (RF), flow cytometric light scatter, and spectrophotometry to analyze cells. Input samples aspirated via probe; cells pass through aperture/sensing zone; electronic pulses and light scatter signals generated. System Manager processes digitized signals via algorithms to identify cell clusters, calculate counts, and generate histograms/flags. Output: CBC, differential, reticulocyte, and body fluid parameters displayed on workstation. Used in clinical laboratories by trained personnel. Output assists clinicians in hematological screening and diagnosis. Benefits: rapid, automated, standardized quantitative blood analysis.

Clinical Evidence

Bench testing only. Studies included accuracy/comparability (whole blood and body fluids), reproducibility (long-term imprecision), repeatability (short-term imprecision), linearity, carryover, and specimen stability. Performance demonstrated equivalence to the predicate device and manual reference methods. Clinical sensitivity and specificity for WBC differential flagging were equivalent or improved compared to the predicate.

Technological Characteristics

Benchtop or floor-stand automated hematology analyzer. Measurement principles: aperture impedance (Coulter Principle), spectrophotometry (HGB), and VCSn technology (DC impedance, RF conductivity, laser light scatter/absorbance). Connectivity: LIS integration via workstation. Software: PC-based workstation (Windows XP) with embedded analyzer application. Reagents: cyanide-free diluent, lyse, diff pack, retic pack, and cleaner.

Indications for Use

Table 5: DxH 800 test panels, reported parameters and sampling methods ### Test Principle The Coulter Principle of automated cell counting and sizing is used in the analysis of the whole blood and body fluid specimens. Each cell suspended in a conductive liguid (diluent) acts as an insulator. As each cell goes through the aperture, it momentarily increases the resistance of the electrical path between two submerged electrodes on either side of the aperture. This causes a measurable electronic pulse. While the number of pulses indicates particle count, the amplitude of the electrical pulse is proportional to the cell volume. These pulses are sent to the Signal Conditioner for analog to digital conversion. Pulse counts and digitized pulse measurements are sent to the System Manager for processing by the algorithms where the reported parameter values, flags and histograms are generated. {7}------------------------------------------------ The lytic reagent used for the white cell count prepares the blood so the system can count leukocytes and measure the amount of hemoglobin. The lytic reagent rapidly and simultaneously destroys the erythrocytes and converts a substantial proportion of the hemoglobin to a stable pigment while it leaves leukocyte nuclei intact. The absorbance of the pigment is directly proportional to the hemoglobin concentration of the sample. Hemoglobin is measured photometrically at 525 nm using the sample from the white cell analysis. Clean diluent is introduced into the cuvette during each operating cycle and is used as a blank in the calculation of the HGB. The COULTER® VCSn technology is used to determine the white cell differential, nucleated red blood cell count and reticulocyte parameters along with associated flags, messages, histograms and dataplots. The sample preparation and analysis uses specific reagents and analytical processes for the WBC differential, NRBC and Retic analysis. The prepared sample is delivered to the flow cell for sample detection. As the cells pass through the sensing zone, a diode laser illuminates the particles causing light scatter and light absorption. Simultaneously to the light scatter measurements, cell volume and cell conductivity are also measured. The data collected during each of the analytical processes is transferred to the System Manager where the digital raw values are processed by the algorithm using mathematical approaches designed for finding optimal separation between clusters of data. The identified clusters are used to calculate the frequency of cells within each population, generate parameter values, flags, histograms and data plots. ### 6.0 Intended Use: The UniCel® DxH 800 COULTER® Analyzer is a quantitative multi-parameter, automated hematology analyzer for in vitro diagnostic use in screening patient populations found in clinical laboratories.
