Abstract
Red cell concentration is the main determinant of bulk blood viscosity. the evaluation of other determinants of blood rheology may require elimination of differences due to hematocrit alone. A simple and efficient procedure is described for calculating blood viscosity at a standard hematocrit, based on plasma viscosity, native sample hematocrit and whole blood viscosity at native hematocrit. The method considers individual variations of the viscosity – hematocrit relationship, as well as its dependence on shear rate.
