Sysmex cell counter principle?

Sysmex cell counters, including the XP-3000, operate on well-established principles of hematology analysis. These principles involve electrical impedance, optical measurement, and fluorescence flow cytometry. Here’s a detailed explanation of each principle:

Electrical Impedance (Coulter Principle)

Electrical impedance is one of the primary methods used in Sysmex cell counters for counting and sizing cells.

  1. Basic Principle:

    • Cells suspended in a conductive fluid pass through a small aperture.
    • As each cell passes through the aperture, it displaces its volume of the conductive fluid, creating a change in electrical resistance (impedance).
    • This change in impedance generates a voltage pulse, which is proportional to the cell volume.

  2. Applications:

    • Used for counting red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs).
    • Helps determine cell size distribution (e.g., Mean Corpuscular Volume (MCV), Platelet Volume).

Optical Measurement

Optical measurement techniques are employed to provide additional data about the cells, enhancing the accuracy of the analysis.

  1. Basic Principle:

    • A laser or light source is directed at the cells as they flow through a narrow stream.
    • The cells scatter the light, and the pattern of light scatter is detected and analyzed.

  2. Applications:

    • Forward Scatter (FSC): Related to cell size.
    • Side Scatter (SSC): Related to cell granularity and internal complexity.
    • Provides data for differentiating between different types of white blood cells in the differential analysis (e.g., lymphocytes, monocytes, granulocytes).

Fluorescence Flow Cytometry

More advanced Sysmex analyzers may incorporate fluorescence flow cytometry, which uses fluorescent dyes to label specific cell components.

  1. Basic Principle:

    • Cells are stained with fluorescent dyes that bind to specific cellular components (e.g., DNA, RNA).
    • As cells pass through a laser beam, the fluorescent dyes are excited and emit light at different wavelengths.
    • The emitted light is detected and measured by photodetectors.

  2. Applications:

    • Provides detailed information about cell composition and function.
    • Used for more sophisticated analyses, such as reticulocyte counting and immature granulocyte detection.

Combining Techniques

Sysmex cell counters often combine these techniques to provide a comprehensive analysis of blood samples.

  1. Three-Part Differential Analysis:

    • Combines electrical impedance and optical scatter measurements to differentiate between lymphocytes, monocytes, and granulocytes.

  2. Red Blood Cell and Platelet Analysis:

    • Uses electrical impedance for counting and sizing.
    • Optical measurements provide additional data on cell morphology.

  3. Hemoglobin Measurement:

    • Typically measured using a colorimetric method.
    • Blood cells are lysed to release hemoglobin, which then reacts with a reagent to form a colored compound.
    • The intensity of the color is measured and correlated with hemoglobin concentration.

Quality Control and Calibration

Sysmex cell counters include built-in quality control and calibration functions to ensure the accuracy and reliability of results.

  1. Quality Control:

    • Regular quality control checks are performed using control materials with known cell counts and properties.
    • The system compares the measured values to the expected values and flags any discrepancies.

  2. Calibration:

    • Calibration is performed using standards to ensure the accuracy of measurements.
    • Both automatic and manual calibration options are available.
