Heska cbc-diff veterinary hematology system
System Overview (From Manual)-
The HESKA CBC-Diff Veterinary Hematology System is a fully automated multi-species hematology analyzer used for in vitro testing of whole blood.
Complete blood counts (CBCs) are performed by simply entering a patient identification number and selecting the appropriate species. Other functions such as calibration and cleaning, are accessed via software menus.
Two external reagent reservoirs are used, one for isotonic diluent and one for a cyanide-free lysing solution. Reagent volumes are monitored via liquid sensing probes. When reagent levels become low, an appropriate message is displayed on the analyzer screen.
A sample memory is available that retains approximately 250 samples. This memory is protected against main power failures. Sample search, selective printing and QC options are available from this menu.
The HESKA CBC-Diff System measures up to 16 parameters using whole blood from an EDTA blood collection tube or a 20 ul capillary tube with True20 Sampling. The following parameters are directly measured by the system:
Total Red Blood Cell Count (CBC)
Total White Blood Cell Count (WBC)
Mean Cell Volume of RBCs (MCV)
Hemoglobin Concentration (HGB)
The following parameters are derived from the measured parameters:
Size distribution histograms of PLT, RBC, WBC
Mean Cell Hemoglobin Concentration (MCHC)
RBC Distribution Width (RDW)
Lymphocyte concentration in absolute number and percentage (LYMF)
Mid-sized cells (e.g. monocytes) in absolute number and percentage (MONO)
Granulocyte concentration in absolute number and percentage (GRAN)
For cell counting and sizing, the HESKA CBC-Diff System employs the electronic impedence method. A colorimetric technique is used to measure hemoglobin. A sophisticated microprocessor continually checks the test process for irregularities and after data is generated, finalizes the calculation of patient results. Numeric results, size distribution histograms and appropriate flags or messages are printed out at the end of the test.
For data output, the HESKA CBC-Diff System comes equipped with both parallel and serial outputs, which are user programmable. Different print formats are selected from several software options.
