8. TECHNOLOGY
The innovative technology of the MYTHIC 22 is covered by six pending patents. A new innovative concept of
optical measurement system and a unique lysing reagent were developed to obtain a small and powerful
analyzer.
8.1 DETECTION PRINCIPLE
8.1.1 WBC, RBC, PLT Counting
The counting of the cellular elements in a blood sample is done with the impedance technique.
This technique is based on the modification of the impedance of a calibrated aperture soaking in an
electrolyte and going through a constant course delivered by two electrodes, located on both sides of the
aperture.
A vacuum applied on a side of the aperture allows the cells passage. They oppose their physical volume to the
course passage. A voltage impulse is registered at the electrodes terminal. The height of this impulse is
proportional to the cell volume.
