Abstract: We have studied some rheological parameters in different clinical status by using two coaxial viscometers. The Contraves Low Shear sinus 30 allows available shear rates range from γ˙ (128s-1 to 0.0175 s-1), and the parameters studied were viscoelastiticy, thixotropy and blood viscosity. The Ecktacytometer11Technicon is another method for measuring cell deformation in couette flow. The aim of our study was to compare these two technics, to consider their clinical interest and finally to visualize an eventual correlation.

Keywords: blood viscosity, blood thixotropy, blood viscoelasticity, erythrocyte deformability, diffractometry
