Patent ID: 7043289

Claim:
A method for use in non-invasive measurements of chemical compositions of a patient's blood, comprising: creating a state of blood flow cessation of the patient's blood within a measurement region of the patient's body and maintaining the blood-flow cessation state during a predetermined time period which is insufficient for irreversible changes to occur in the body, thereby affecting an erythrocytes' aggregation process in the measurement location defining a change in characteristics of the patient's blood; applying an external electromagnetic field to the measurement region within said predetermined time period, and obtaining measured data representative of the time dependence of a response of the blood in the measurement region to said external electromagnetic field, the measured time dependence including an initial time period of the response variation and an asymptotic time period of relatively slow changes of the response as compared to the initial time period; and analyzing the measured data for determining one or more parameters of the patient's blood, including extracting characteristics associated with the erythrocytes aggregation process during the state of the blood flow cessation.
