WebSep 27, 2024 · The viscosity of whole blood increases as the red cell count and hematocrit increase. 22 Whole-blood viscosity is ∼4.5 cP at a shear rate of 200 per second. At high shear rates, red cells disperse, form ellipsoids, and flow becomes streamlined. However, as the hematocrit exceeds 50%, there is a rapid increase in viscosity. WebSimilar to those in whole blood, the tracings in the samples diluted with NaCl can be separated into three distinct stages: a stable liquid state with low viscosity, a rapid transforming state and a stable gel state with high viscosity. The data from whole blood and blood diluted with NaCl were fitted into S-curves.
