What is the principle of impedance? Name at least two instruments that employ this method for blood cell counting
What will be an ideal response?
Answer: Impedance relies on the principle of increased resistance that occurs when a blood cell with poor conductivity passes through an electrical field. The number of pulses indicates the
count, and the height of the pulses indicates the relative volume of each cell passing through the photodetector. Instruments that use this method are Coulter ® Gen-S, Coulter ® LH series, Sysmex XE-2100TM, and Abbott CELL-DYN Sapphire ®.
