Drew Scientific Evolution Automated Hematology System Specifications
| System Software |
| The Evolution 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 Evolution 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 |
| Evolution 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. |
| Scientific Principle |
| Electrical resistance for cell counting and sizing (WBC, RBC, Plt). 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: 70uL whole blood using closed or open tube mode. Capillary Blood : 25uL whole blood. |
| Dilution system |
| In order to maximize 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 |
| 60 samples per hour in direct sampling mode |
| Reagent Packs |
| EVO-PAC 200 : approximately 200 tests per pack at 10 samples per day, depending on lab operating procedures. EVO-PAC LV (for low volume laboratories) : approximately 100 tests per pack at 5 samples per day, depending on lab operating procedures. |
