Operation :
Scientific Principle :
Multi-dimensional optical scattering using stable laser diode light source to optimize the measurement of WBC differential
Electrical resistance for counting (WBC, RBC, Plt) and sizing (Plt,RBC)
Optical absorbance of cyanmethemoglobin for hemoglobin measurement (there is also an optional cyanide-free reagent).
Full CBC with 5 part differential in under one minute.
Sample Volumes :
Blood samples must be collected in EDTA tubes. Depending on how the 2280 is operated, the system requires :
| Direct mode Sample saver mode Automatic sampler** |
180 µL whole blood 80 µL whole blood 180 µL whole blood |
An optional 30 position autosampler is available.
The Autosampler mixes, reads the barcode, pierces the tube cap and automatically aspirates the sample.
High precision ceramic
shear valve and computer controlled diluent dispenser. Automatic rinse
inside and outside of the sample probe prevents carryover and reduces
risk of transmission of blood borne pathogen to operators.
Sensors :
Laser diode illuminated flow cytometer with three, solid state sensors and one PMT tube for WBC differential.
| WBC aperture | 100 µm dia x 75 µm length |
| RBC/Plt aperture | 78 µm dia x 55 µm length |
The Plt/RBC channel features the patented "von Behrens" silencer that eliminates RBC recirculation which interferes with low Plt counts in conventional aperture designs.
System Software :
The 2280's easy to use software gives rapid access to all patient information including full blood counts, demographics and patient history. QC, calibration and reporting routines are all a few key strokes away.

CD4 Testing :
Drew is proud to offer a unique, fully automated, closed tube sampling, whole blood method for CD4 and CD4% testing.
The CD4% test is crucial in optimising anti-retroviral therapy provided to pediatric and adult HIV/AIDS patients.
| The 2280/CD4% Method | Other CD4 Only Methods | Benefit | |
| Sample loading | Load the blood tube directly into the instrument | Remove cap from blood tube Pipette blood into test tube |
No exposure to potential bio-hazardous material | Pre-analytical stages | None Instrument performs all pipetting, incubating and sample handling steps automatically |
Add reagents to test tube Allow test tube to incubate offline Load the test tube into the instrument |
No exposure to potential bio-hazardous material No accuracy errors introduced by manual sample handing |
| Result interpretation | Fully automatic data analysis and result generation | Operator interprets cytogram and manually gates clusters to allow enumeration of cells | No inaccuracies due to manual gating of cell clusters |
| Reagent storage | Reagents are stored with the instrument | Reagents stored in refrigerator | No refrigeration required |
| Supplementary equipment | No pipettes are required | Calibrated pipettes and pipette tips must be available | Reduced costs |
| Quick training | Operator trained within a few hours | Operator attends formal training over a few days | Your can produce accurate results from day one |
|
This test is available for the first time in a completely automatic format with no predetermination, sample manipulation or post measurement operator involvement. An operator with brief training is able to perform the testing protocol by simply loading the automatic sampling module and selecting the analyse command. Once the sample is loaded the user is entirely free to perform other laboratory tasks. On completion of the analysis a CD4 and CD4% report together with a comprehensive 22 parameter hemogram is available for reporting to the ordering physician. |

Biohazard exposure
High throughput and Ease of use
