What technology does the VetScan HMII/HM2 utilize?
The HMII/HM2 uses impedance technology to detect cells: electrically neutral blood cells pass through an electrically charged aperture thereby generating a “pulse”. The decrease in electrical conductance is directly proportional to the cell volume. This size discrimination, along with susceptibility to various lysing agents distinguish the basic cell types (red cells, white cells, platelets). The size of the HMII/HM2 aperture was specifically designed to accommodate veterinary blood cells, thereby providing optimal differentiation.
