1. A method of optical measurements of at least one desired parameter of a patient'"'"'s blood, comprising:

  • providing a state of blood flow cessation of the patient'"'"'s blood within a measurement region, and maintaining the blood-flow cessation state during a predetermined time period;

    performing measurement sessions within said predetermined time period, each measurement session including at least two measurements with different wavelengths of incident light, and obtaining measured data representative of the time dependence of light response of the blood in the measurement region;

    analyzing the measured data for determining said at least one desired parameter, extracted from optical characteristics associated with erythrocytes aggregation process during the state of the blood flow cessation.
