Claim:
1. A method of characterizing at least one hemostatic function of a blood sample, said method comprising: testing a first portion of the blood sample, wherein said testing comprises causing, by a processor, generation of a deformation of the sample by applying a series of acoustic pulses to the first portion, wherein at least one of the pulses is of sufficiently high intensity to induce physical displacement of the first portion; estimating, by the processor, based on one or more received measurements from the testing of the first portion, a first quantitative value of said hemostatic function of the first portion, wherein the first quantitative value describes a viscoelastic property of the first portion; treating a second portion of the blood sample with a treatment to vary said hemostatic function from said first quantitative value of the hemostatic function of the first portion having been estimated; testing the second portion of the blood sample having been treated, wherein said testing comprises causing, by a processor, generation of a deformation of the sample by applying a second series of acoustic pulses to the second portion, wherein at least one of the pulses is of sufficiently high intensity to induce physical displacement of the second portion; and estimating, by the processor, based on one or more received measurements from the testing of the second portion, a second quantitative value of said hemostatic function of the second portion, wherein the second quantitative value describes a viscoelastic property of the second portion; wherein compared results of said first quantitative value with said second quantitative value are used, by a processor, to evaluate viscoelastic parameters associated with an effect of said treating on said hemostatic function of the blood sample, wherein the viscoelastic parameters are derived from the compared results.
