Background :

Drew Scientific has been making leading edge and top quality CBC systems for over 15 years.
The Excell 16/18 offers a reliable alternative for a 3 part differential.

The Excell 16 version is for sale in the USA.
The Excell 18 version is for sale in the Rest of the World.


Features :

  • 16 or 18 parameters
  • 60 samples per hour
  • Sample size flexibility satisfies a wide range of end user requirements
  • Large LCD with histograms on screen
  • User friendly operator interface
  • Data management stores up to 200 sample records and QC statistics
  • User interface with multilanguage capability

Parameters :

WBC,  Lymp#,  Gran#,  Mids#
Lymp%,  Gran%,  Mids%
RBC, Hgb, Hct, MCV, MCH, MCHC, RDW, Plt, MPV, Pct*, PDW*
(* Not available in the USA: for research only)
The system also displays :
WBC histogram
Plt histogram
RBC histogram


Operation :

Scientific Principle :
Electrical resistance for cell counting (WBC, RBC, Plt) and sizing (Plt,RBC).
This is combined with optical absorbance of cyanmethemoglobin for hemoglobin.
The technology combines to give a full CBC with 3 part differential in just under one minute.

Sample Handling :
Blood samples must be collected in EDTA tubes. The following sample sizes are required:
Direct mode : 125 µL whole blood
Sample saver mode : 60 µL whole blood
Pre-dilute Mode : 80 µL whole blood

Dilution system :
In order to maximise performance and reduce instrument down-time a high precision ceramic shear valve and computer controlled reagent dispenser are used. Automatic rinse inside and outside of the sample probe prevents carryover and reduces risk of transmission of blood borne pathogen to operators.

Throughput :
Minimum 60 samples per hour in direct sampling mode


System Software :

The Excell 16/18 uses powerful but user friendly software. Every operator request such as counting, retrieveing results from the memory, QC calibration or printing is only a few key strokes away.

Patient identification : 9 digit keypad entry
Patient data storage : 200 results with histograms
Report format : User selectable
Calibration : Automatic or manual
Units : The user can select MKS, SI, SI modified, or Chinese
Patient normal range : User defined
Patient action limits : User defined
Quality Control :
A comprehensive onboard QC package allows optimal monitoring of system performance. The Excell 16/18 allows two lots with three levels each. Up to one result for each level per day for 100 days or a maximum of 300 results for each lot can be stored onboard. QC data can also be viewed in a monthly Levy-Jennings plot. A log of QC data with automatic calculation of mean, SD and CV can be printed.
Operation alerts : Excell 16 / 18 users get full feedback on operation of the system and sample being analyzed with a range of diagnostic alerts.
Maintenance : To monitor maintenance of the system a maintenance log is available.
Language : Multi language capability.

Specifications :

Precision :
  Level Units CV
WBC 8.0 x 10³ cells/µL < 1.5 %
RBC 5.0 x 106 cells/µL < 1.0 %
Hgb 16 g/dL < 1.0 %
MCV 90 fL < 1.0 % 
Plt 250 x 10³ cells/µL < 3.0 %
Linearity :
  Range Units Linearity
(whichever greater)
WBC 0.1 to 99.9 x 10³ cells/µL ± 0.2 or ± 2%
RBC 0.02 to 9.99 x 106 cells/µL ± 0.05 or ± 2%
Hgb 0.0 to 30 g/dL ± 0.1 or ± 2%
MCV 40 to 150 fL ± 1.5 or ± 2%
Plt 10 to 1000 x 10³ cells/µL ± 10 or ± 5.0%
Plt 10 to 2500 x 10³ cells/µL ± 15 or ± 7%

To optimize performance the Excell 16/18 automatically corrects the Plt result when an interference between the Plt and RBC population is detected.

Sensors :
  WBC aperture :  100 µm dia x 75 µm length
  RBC/Plt aperture : 78 µm dia x 55 µm length
The RBC/Plt channel features the patented "von Behrens" silencer that eliminates RBC recirculation which interferes with low Plt counts in conventional aperture designs.
Display : Large (122mm x 92mm) liquid crystal display with backlight.
Printer : External inkjet or impact. Several selectable emulations.
