Background :

Drew Scientific has been making leading edge and top quality CBC systems for over 15 years.
The Drew-3 is the latest innovative offering.


Features :

  • 16 parameters
  • 60 samples per hour
  • 10 µL sample size (whole blood) + pre-diluted mode
  • Large LCD color touchscreen for ease of use
  • Data management stores up to 1000 sample records and QC statistics
  • User-friendly operator interface with multilanguage capability
  • Low reagent consumption

Parameters :

WBC,  Lymp#,  Gran#,  Mids#
Lymp%,  Gran%,  Mids%
RBC, Hgb, Hct, MCV, MCH, MCHC, RDW, Plt, MPV
The system also displays :
WBC, Plt and RBC histogram


Operation :

All operations are controlled via the large touch screen.
This includes start-up and shut-down, run samples, datalog, QC, Reagents.
Four different operator levels are possible including Lab Manager and Lab Tech.
Operators are logged at start-up or when a new operator takes over.

Sample Handling :
Blood samples must be collected in EDTA tubes. Sample sizes :
Direct mode : 10 µL whole blood
Pre-diluted / Capillary : 25 µL into 0.5ml of diluent using a built in diluent dispenser

Throughput :
60 samples per hour in direct sampling mode

Reagents :
A compact 3 reagent pack is provided. Packs are coded with lot number and expiry date to give full traceability.

QC
Six controls levels, 3 months each. Assay values can be entered via the keypad or loaded from a USB key. Automatic calculation of mean, SD and CV% (possible to reject bad samples). Levey Jennings plot per level. It is possible to upload results to USB key for peer to peer analysis.


System Software :

The Drew-3 is controlled via a large colour touchscreen.
The software is designed to make the instrument as easy to use as possible.
Up to 1000 sample results can be stored on the system and results can be backed up on a USB key (flash disk).
