Abstract:
A method for determining the viscosity of the circulating blood of a living being using an adulterated blood sample from the living being, said method comprising the steps of:(a) dividing the population of living beings into a plurality of categories; (b) selecting a predetermined number of living beings in each of the categories and obtaining a first blood viscosity vs. shear rate profile for each of the living beings using a circulating blood viscometer; (c) obtaining a blood sample from each of said predetermined number of living beings and then adulterating each of the blood samples; (d) inputting each of said adulterated blood samples into a conventional blood viscometer and obtaining a second blood viscosity vs. shear rate profile; (e) comparing said first blood viscosity vs. shear rate profile to said second blood viscosity vs. shear rate profile for each of said blood samples to determine a correlation factor, ycf, for each of the living beings in each one of said plurality of categories; (f) determining an average correlation factor, Ycf, for each one of said plurality of categories from said correlation factors, ycf, in each one of said plurality of categories, said average correlation factor, Ycf, being applied to any subsequent blood viscosity vs. shear rate profile obtained from a conventional blood viscometer to obtain the circulating blood viscosity.
