RESUMO
We have measured the AC impedances of blood samples from 30 healthy adults with the Agilent 4294A impedance analyzer at frequency ranging 0.01-100MHz. At the same time, we measured the erythrocyte sedimentation rate (ESR), hematocrit (HCT), plasma fibrinogen (FIB), blood glucose (BG) and D-dimer. Then we analyzed the correlation between ESR and dielectric parameters of blood by linear correlation analysis, and used multiple regression analysis to reveal the influence of these hematological data on dielectric spectral characteristics of whole blood cell when these data were available. Statistical analysis showed that ESR had a linear correlation with the part of dielectric parameters in whole blood cell. The Multiple linear regression analysis indicated that HCT and BG had an influence on dielectric spectral characteristics of human whole blood cell, and HCT was the major factor in haematological parameters that influenced dielectric spectral characteristics of whole blood cell.
