Abstract: Power law regression analysis of the form γ = A·xB was performed on the dependence of blood viscosity on shear rate. By this way a blood viscosity versus shear rate curve could be comprised and expressed as two characteristic regression coefficients. Analysis of the dependence of A and B on hematocrit yields normal values for blood viscosity versus shear rate for each specific hematocrit, so blood viscosity can be evaluated for being normal or not, at the hematocrit of the blood sample itself.
