1. A method of evaluating the ability of a fluid to clot, comprising:
- inducing flow of a fluid within a fluid container by exerting force on the fluid;
measuring a baseline flow rate of the fluid before inducing clotting;
inducing clotting within the fluid;
measuring a secondary flow of the fluid during or after inducing clotting and while the fluid is acted upon by the force; and
determining a degree of clotting in the fluid based on a difference between the baseline flow rate and the secondary flow rate of the fluid.

Abstract
A method of evaluating a property of a physiological fluid suspension comprises measuring a value of the property of a liquid portion of the physiological fluid suspension via light scattering, and comparing the measured value with a reference value to evaluate the property of the liquid portion of the physiological fluid suspension.

16. A system for determining a degree of clotting within a fluid, comprising:
-
a container for retaining a fluid therein; a flow inducing system operable to induce flow of the fluid retained within the container both before and after the fluid undergoes clotting; a clot inducing system, operable to induce clotting in the fluid retained within the container; and a fluid flow measurement system operable to measure at least a baseline fluid flow rate before inducing clotting of the fluid retained in the container, and a secondary flow rate during or after inducing clotting of the fluid retained in the container; wherein a degree of clotting of the fluid is determined by comparing the baseline flow rate of the fluid and the secondary flow rate of the fluid. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A method of evaluating the ability of a fluid suspension to clot, comprising:
-
inducing flow of a fluid suspension within a fluid container by exerting force on the fluid; measuring a baseline flow rate of the fluid suspension before inducing clotting; inducing clotting within the fluid suspension; measuring a secondary flow of the fluid suspension during or after inducing clotting and while the fluid suspension is acted upon by the force; determining a rate of change of flow rate of the fluid suspension based on the baseline flow rate and the secondary flow rate of the fluids; and determining a degree of clotting in the fluid suspension based on the rate of change of flow rate of the fluid suspension. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
