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.
Claims35
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.

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.
