DETECTION PRINCIPL

1.6.1

Detection Principles of WBC, RBC, PLT

The count principle of the instrument is based on the measurement of changes in electrical resistance produced by a particle passing through an aperture sensor. a) The sample blood is diluted in a conductive liquid. As blood cells are non-conductive, the diluent is a good conductor. There are big differences between them. b) When the diluent passes through the aperture sensor, electrodes are submerged in the liquid on each side of the aperture to create continuous current. c) When cells pass through the aperture, the resistance between the electrodes increases as the cell volume increasing, as is shown in figure 1-4.According to the Ohm Formulary: U=RI (U=Voltage I=Current R=Resistance).If

I is a constant, U increases as the cell volume

increasing. d) Passing through the magnification circuit, the voltage signal will be magnified and the noise will be filtered, then you will gain the analytical results, as shown in figure 1-4. e) One count pool and the detection circuit count the WBC. Another count pool and the detection circuit count the RBC and PLT. The microprocessor of the instrument calculates and analyzes the cells (WBC, RBC, PLT), and then gives out the histograms. f)

PLT count adopts advanced liquid, electronics and software system. It settles the repetitive count of the cells on the side of the aperture count area.

Instrument Introduction

Figure 1-4

1.6.2

Principles of HGB Measurement

Adding lyse in the blood, the red blood cell will rapidly be broken down and release hemoglobin. Hemoglobin and lyse form a new mixture, which can absorb the wavelength of 540nm.Measure the absorbency. Through the comparison of the absorbency between the pure diluent and the sample，the concentration of the sample hemoglobin is calculated.

1.6.3

Volume Distribution of Blood Cell

When different types of cells pass through the aperture sensor, there will be different electrical pulse height. Because of the evident difference of the cells sizes, the instrument is able to differentiate the white blood cell, red blood cell and platelet by its pre-set program. The volume distributions are as follows: WBC

120～1000fL

RBC

82～98fL

PLT

2～35fL

The leucocytes disposed by lyse can be divided into three types, according to their volumes: lymphocyte (LYM), mid-sized cell (MID), Granulocyte (GRAN). LYM MID

35～90 fL 90～160 fL 13

Instrument Introduction GRAN

1.6.4

160～450 fL

Results and Calculation of Parameter Measurement

The parameters of the sample blood test can be described in three ways: a) Measured directly, such as WBC, RBC, PLT, HGB. b) Derived from histograms, such as LYM%, MID%, GRAN%, MCV, RDW-SD, RDW-CV, MPV, PDW, P-LCR. c) Calculated, such as LYM#, MID#, GRAN#, HCT, MCH, MCHC, PCT. The derivation of the formularies as follows: z

MCV derives from histograms and the instrument collecting and classifying the erythrocytes according to its volume. It is determined by measuring the average volume of individual erythrocytes, and the unit is fL.

z

RDW represents the volume distribution of the erythrocyte populations, derived from the RBC histogram. It can be expressed by the coefficient variation of the erythrocyte volume as RDW-CV, and the unit is %.It can also be expressed in standard deviation of the erythrocyte volume as RDW-SD, the unit is fL.

z

MPV is the average volume of individual platelets, derived from the PLT histogram. It represents the mean volume of the PLT populations and can be expressed in fL.

z

PDW derives from the PLT histogram. It represents the geometry standard deviation (10 GSD) of the volume of the PLT populations.

z

P-LCR derives from the PLT histogram. It represents the ratio of the larger PLT and the unit is %.
