We have measured the conductivity, the apparent viscosity and shear stresses of RBC suspensions and whole blood prepared after treatment with aggregation inducing agent polyethyleneglycol. A time course of blood conductivity recorded under different flow conditions provides experimental description of RBC aggregation-desaggregation processes and other cell-cell interactions. The results show that the blood conductivity is strongly dependent on the considered blood factors and is influenced by flow, shear rates, concentration and cell deformability.
