Mode of Operation of DxH 560 Analyzer
Open and close tube sampling
3
Mode of Operation of DxH 520 Analyzer
Autoloader, 50 tube continuous feed capacity, open-tube mode
4
Sample volume of DxH 520 and DxH 560 Analyzer
17 ul of venous or micro-collected
5
Throughput of DxH 520 and DxH 560 analyzer
55 closed tube samples per hour, 60 open tube samples per hour
6
Menu/Test Parameters of DxH 520 and DxH 260 Analyzer

7
It integrated control that enables monitoring of the system's performance and calibration status for all CBC and Diff parameters.
DxH 520/560 Controls
8
True or False: DxH 520/560 are available in three levels (low, normal, and high)
True
9
DxH 520/560 control Open Stability
15 days
10
DxH 520/560 controls Storage
2 - 8°C
11
White Blood Cell Method
Coulter Principle
12
Red Blood Cell Method
Coulter Principle
13
Hemoglobin (HGB) Method
Photometric Measurement
14
It is measured directly, multiplied by a calibration factor
White Blood Cell and Red Blood Cell (Coulter Method)
15
It transmittance of light at 545 nm through lysed WBC bath, compared to the transmittance of the same light through a reagent blank. The system converts this ratio to the HGB value using a calibration factor
Hemoglobin (Photometric Measurement)
16
Hematocrit Method
Calculated
17
Hematocrit Calculation
HCT (%) = (RBC x MCV)/ 10
18
Mean Corpuscular Volume (MCV) Method
Derived from RBC Histogram
19
The average volume of individual RBC's derived from the RBC histogram, multiplied by a calibration factor
Mean Corpuscular Volume (MCV)
20
Mean Corpuscular HGB (MCH) Method
Calculated
21
Mean Corpuscular HGB (MXH) Calculation
MCH (pg) = (HGB/RBC) x 10
22
Mean Corpuscular HGB Conc. (MCHC) Method
Calculated
23
Mean Corpuscular HGB Conc. (MCHC) Calculation
MCHC (g/dL) = (HGB/HCT) x 100
24
Red Cell Distribution Width (RDW) Method
Derived from RBC Histogram
25
The size distribution spread of RBC population derived from the RBC histogram
Red Cell Distribution Width (RDW)
26
Platelet Method
Coulter Principle
27
The number of platelets derived from the PLT histogram, multiplied by a calibration factor
Platelet (Coulter)
28
The average volume of individual platelets derived from the PLT histogram, multiplied by a calibration factor
Mean Platelet Volume (MPV)
29
Mean Platelet Volume (MPV) Method
Derived from the PLT histogram
30

38
Eosinophils percent Calculation
[EO events/(NE+LY+MO+EO+BA events)] x 100
39
Basophil percent Calculation
[BA events/(NE+LY+MO+EO+BA events)] x 100
