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:
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.
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.
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.
PDW derives from the PLT histogram. It represents the geometry standard deviation (10 GSD) of the volume of the PLT populations.
P-LCR derives from the PLT histogram. It represents the ratio of the larger PLT and the unit is %.
14
HCT(%)= RBC×MCV/10
MCH(pg)= 10×HGB/RBC
MCHC(g/L)= 100×HGB/HCT
PCT(%)= PLT×MPV/10
LYM% = 100 x AL / (AL+AM+AG)
MID% = 100 x AM /(AL+AM+AG)
GRAN% = 100 x AG/ (AL+AM+AG)
LYM# = LYM% x WBC/100
Instrument Introduction
MID# = MID% x WBC/100
GRAN# = GRN x WBC/100
AL: Number of cells in LYM area; AM: Number of cells between lymphocyte and granulocyte area; AG: Number of cells in GRAN area.

CHECKING ITEMS BEFORE MAINTENANCE
Items required for checking before maintenance: Ambient Temperature:
15~35℃
Temperature of the reagent:
15 ~30℃
Humidity:
10~90%
Atmospheric Pressure:
86.0kPa~106.0kPa
If the temperature is below 15℃,the activity of the reagent will reduce. It will weaken the capacity of dissolving the blood. In a certain time, it can not break down the red blood cell membranes into 2fl cellular debris. At lower temperature conditions, the red blood cell debris will gather together. It will affect the measurement of leukocyte, resulting in the count value of WBC increasing .It will also affect the measurement of HGB, resulting in the count value of HGB increasing. Checking for Sample Blood Sample Collection: Observe whether the operator uses correct method to collect the blood
(Operating as PE-6800 FULLY AUTO HEMATOLOGY ANALYZER OPERATION MANUAL /Chapter 3/Section 3.5 Preparation For Sample Collection ), and whether the sample is stored in the container filling with EDTA.K 2O.H2O anticoagulant. Sample Storage: After the sample blood is well-mixed, test on the instrument promptly. As time
goes by, the volume and density of the cells will change. The environment and the patient determine the varying rate of the volume and density. If the sample is placed a long time at room temperature, the volume of RBC will increase, and the MCV, RDW, PDW will be affected, and the PLT will easily gather together. Affection of WBC Classification: To get the exact measuring results, the venous blood sample
measurement must be completed within 4 hours. If the sample blood is placed a long time at room temperature, the total number of WBC may change little, but the classification is inaccurate.
7.3
BACKGROUND CHECK
Background Check: This item can ensure the measurement and the calculated data won’t be
affected by reagent empty. If the background value exceeds the permissive area, the measured and calculated data will be inaccurate. The permissive range of the background test results is 38

Background Test Method: When power-on, suggested to run background test, you can also
execute background test as you need. The operation steps are as follows: a)
In the blood cell analyzer window, press “Info” button, and pops up the information edit window. Then click the item textbox, change the ID as 999999999.then press “OK”, return to blood cell analyzer window.
b)
Background count in venous or capillary mode, press the “START” key below the sample needle directly for background count. In prediluted mode, the sample needle aspirates some non-contaminated diluent from the chamber for background count. The diluent pick-up method as follows(Analyzing the sample in prediluted mode, it is also necessary to dilute sample with the diluent which is prior picked-up in this method):
In main operation area, press the right key of the mouse, pops up the menu. In menu operation area, select “Sample Mode/ Prediluted” to set the sample mode as prediluted mode. In main operation area, press the right key of the mouse, pops up the menu. In the menu operation area, select “Diluent”. Place a clean empty chamber or tube under the sample needle, press “START” key to dispense the diluent into the chamber. Press the “START” key once, the diluent
is dispensed into the chamber or tube once (The quantity can be used for background count in the second prediluted mode). Press “Exit” button to return to the main operation area. Affected Factors of Background: 1、
The reagent is dirty.
2、
The chamber is dirty.
