4.0 System description :

4.1 Device Description

The ABX MICROS ES 60 is a quantitative, automated hematology analyzer and leukocyte differential counter for in vitro diagnostic use in clinical laboratories. The instrument system is comprised of the analyzer and a suite of analytical reagents that allow for simultaneous quantitative determination of hemoglobin measurement, cell counting, quality control, calibration, and cleaning. The system is a microprocessor controlled hematology analyzer used for the in vitro diagnostic testing of whole blood specimens. It operates in complete blood count (CBC) and Differential (DIFF) mode

4

using a combination of focused flow impedance and light transmission technologies. It is available in Closed (CT) or Open Tube (OT) sampling versions.

4.2 Principles of Operation

The ABX Micros ES 60 principle of automated cell counting and sizing is used in the analysis of the whole blood. Each cell suspended in a conductive liquid (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.

The diluted sample is processed through two different chambers:

  • The RBC / PLT chamber, for the Red Blood Cell (RBC) and Platelet (PLT) detection .
  • The WBC / HGB chamber, for the White Blood Cell (WBC) and Hemoglobin (HGB) counts

Image /page/4/Figure/8 description: This image shows a schematic diagram of a blood analysis system. The diagram includes components such as WBC/HGB, RBC/PLT, and ABX Diluent/Lyse. The diagram also shows the flow of samples and reagents through the system, with arrows indicating the direction of flow. The image includes labels such as CT and OT.

Red Blood Cells (RBC) and Platelets (PLT) Detection:

The blood specimen is diluted in the electrolytic (current conductor) ABX Minidil LMG and pulled through the 50 um calibrated micro-aperture in the mini flow-cytometer. Two electrodes are placed on either side of the aperture. Electric current passes through the electrodes continuously. When a cell passes through the aperture, the electric resistance between the two electrodes increases proportionately to the cell volume.

The impedance variation is measured and allows for the RBC and PLT quantification.

Hemoglobin Measurement:

The lysing reagent breaks down the RBC cell membrane and releases the hemoglobin contained by the cell. The hemoglobin, released by the lysing reagent, combines with the potassium cyanide from the lysing reagent to form a chromogenous cyanmethemoglobin compound. This compound is then measured through the optical part of the WBC/HGB chamber by spectrophotometry at a wavelength of 550 nm.

Hematocrit Measurement:

All the RBC pulses are grouped into various sizes. Each group pulse height is then averaged. All the pulse height averages are then averaged one final time for a mean average of all the RBC pulse heights. This function is a numeric integration of the MCV. The HCT results are given as a percentage of this integration.

Red Distribution Width (RDW) Calculation:

The RDW is calculated from the RBC histogram. It allows to follow the evolution of the width of the RBC histogram in relation to the number of cells and their average volume.

Mean Cell Volume (MCV), Mean Cell Hemoglobin (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC) Calculations:

The MCV is calculated directly from the entire RBC histogram. The MCH is calculated from the HGB value and the RBC count. The MCHC is calculated according to the HGB and HCT values.

Mean Platelet Volume (MPV):

The MPV is directly derived from the analysis of the platelet distribution curve.

White Blood Cell (WBC) Count:

The WBC count is carried out in the WBC/HGB chamber. The detection principle is the same as for RBC.

ABX Minidil LMG reagent preserves and prepares the WBC cell membrane for the differential reaction. The lysing reagent has a differential mode of action on the WBC cytoplasmic membranes.

  • When the lysing reagent reacts with the lymphocytes, the cytoplasm and the . membrane are destroyed. At the end of the lysing action, only the nucleous remains intact and this action results in a smaller volume detected by the instrument.

6

  • When the lysing reagent reacts with the monocyte cytoplasmic membrane, it has an intermediate reaction that empties the cytoplasm from the cell. At the end of the lysing action, the monocyte cells obtained have an intermediate size between the lymphocytes and the granulocytes.
  • When the lysing reagent reacts with the granulocytes, it has a limited reaction due ● to a molecule in their cytoplasmic structure which protects them from the shrinking action of the lyse. This in turn makes the granulocytes the larger of the WBC sub-populations in the cell differentiation.

The three sub-populations of WBCs are placed according to the number of cells and the size of the cells in each group. The lymphocyte, monocyte and granulocyte results are given as a percentage of the entire WBC count.

The granulocytes subpopulation of the WBC contains three sub-populations that contain cytoplasmic granular material which stain various colors when viewed microscopically. They are as followed:

  • Neutrophils
  • Eosinophils
  • Basophils

The distribution of these cells depends on the pathological and physiological conditions of the individuals analyzed.

Pathological cells are placed in different zones within the WBC distribution curve and trigger alarms.

4.3 Modes of Operation

Two models of ABX Micros ES 60 are available.

  • . The Closed Tube (CT) instrument: it has a cap-piercing mechanism. The blood collection tube is placed directly in the analyzer without removing the cap.
  • . The Open Tube (OT) instrument: the cap form the blood collection tube must be removed before analyzing the sample.

4.4 Specimen Identification

Specimen identification is by manual sample identification with the use of a hand held barcode scanner.

4.5 Calibration

Calibration is a procedure that is performed during specific situations such as installation. maintenance or service intervention. It is performed by a HORIBA ABX SAS representative. It ensures that the precision and accuracy of the analyzer are acceptable, so that accurate measurements are performed by the analyzer.

ABX Minocal calibrator (K955925) is used for the ABX Micros ES 60 calibration procedure. Assigned assay values are traceable to reference methods.

7

4.6 Quality Control

Quality control allows the user to monitor a set of analyses based on known sample values and ranges over a period of several months. Statistical computation performed on these populations allows the extraction of qualitative information related to the stability of the instrument.

ABX Minotrol 16 Control (K850755) enables monitoring of system performance for all directly measured and calculated CBC and Diff parameters. Assigned assay values are determined on validated instruments using the appropriate reagents.
