Abstract:
In order to test validity and fea si bility of the impedance spectroscopy analysis method,a series of blood experime n ts have been carried out to study influences of the hematocrit,the plasma conc e ntration and the dextran concentration in suspend medium on the blood impedance and the RBC aggregation.The results show that the blood impedance of lower freq uency R_0 increases with increase of Hctc,the time constant T has little chang e when Hctc hange from 28.9 to 48.9;with the increase of plasma concentration ,t he RBC aggregation radius increases;When the dextran concentration is about 4g/ 100ml,the RBC aggregate reaches its maximum.It suggests that the impedance spe ctroscopy analysis method is a new,effective method to study RBC aggregation.
