The QBC STAR™ POC Haematology System is the simplest solution for patient side testing. An innovative approach employing dry haematology reagents instead of the bulky reagents utilised by other methods. A revolution in patient care- easier, more efficient and virtually problem-free. Measures the Clinically Significant Parameters Most Requested by Physicians: - haematocrit
- haemoglobin
- MCHC
- platelet count
- white blood cell count
- granulocyte percentage
- lymphocyte/monocyte count
- lymphocyte/monocyte percentage

Re-read Functionality: The QBC STAR™ now comes with re-read functionality allowing the user to re-read a sample that has already been spun and to access precision as well as accuracy. Troubleshooting is alos made easier as a tube can be removed from the STAR™, assessed and then placed in the analyser again for a second run Patient Identification System: Patient indentification information can be entered simply via the keyboard and barcode scanner Click here for full download |  |
