Abstract (en)
[origin: WO9201934A1] The blood testing apparatus includes a fluid flow control system (38) for moving a fluid containing blood cells through an electromagnetic field, and detecting the change in the electromagnetic field caused by the passing of the blood cell. The fluid flow control system includes a pump (40) and a series of valves (52, 70, 82), all controlled by a controller (43). The pump (40) draws the blood cells through the electromagnetic field. The size of the blood cell can be determined by the measurement of the value of the voltage change resulting from the passage of the blood cell through the electromagnetic field.
