Abstract :
It is determined how impedance is affected by hematocrit, conductivity and electrode configuration in a continuous flow system in vitro. Four-electrode measurements have robust characteristics which require constant geometry but do not require uniform fields or rigid positioning. Findings show that the ratio of red blood cell conductivity to electrolyte conductivity is important in the pattern impedance versus hematocrit
