    3 System Principles 3.1 Introduction The analyzer uses the electrical impedance method to determine the count and size distribution of RBC, WBC and PLT, and uses the colorimetric method to determine HGB. Based on the above data, the analyzer calculates other parameters. 3.2 Analyzer Workflow We have defined the whole operation workflow of the analyzer by its major functions: reagent system, sample loading and distribution, sample preparation, sample measurement,...

  • Page 24: Aspiration

    System Principles 3.3 Aspiration If you want to analyze a whole blood sample, present the sample to the analyzer directly, and the analyzer will aspirate 10μL of the whole blood sample. If you want to analyze a capillary blood sample under the pre-dilute mode, you should first manually dilute the sample (20μL capillary sample needs to be diluted by 0.58 mL of diluent to form a 1:30 dilution), and then present the pre-diluted sample to the analyzer, which will aspirate 183uL of the sample.

  • Page 25: Wbc-Related Parameters

    System Principles Figure 3-1 Metering diagram 3.5.2 WBC-Related Parameters  White Blood Cell count WBC (10 /L) is the number of leukocytes measured directly by counting the leukocytes passing through the aperture. Sometimes there are nucleated red blood cells (NRBC) presenting in the sample. While the lyse will not be able to break their nuclear membrane, these NRBCs will also be counted as WBCs.
  • Page 26 System Principles In the formulae: PL indicates the number of cells falling in the lymphocyte region, PM the number of cells falling in the mid-sized cell region, and PG the number of cells falling in the granulocyte region. All three parameters are presented in 10 When the three percentages are obtained, the analyzer automatically proceeds to calculate the lymphocyte number (Lym#), mid-sized cell number (Mid#) and granulocyte number (Gran#) by below formulae, all parameters expressed in 10...

    System Principles After each analysis cycle, you can either check the WBC histogram in the analysis result area on the "Sample Analysis" screen or review the histogram on the "Review" screen. 3.5.3 HGB Measurement The HGB is determined by the colorimetric method. The diluted sample is delivered to the WBC count bath where it is bubble mixed with a certain amount of lyse, which breaks red blood cells, and converts hemoglobin to a hemoglobin complex.
