Method to determine the speed of sedimentation of blood and other parameters correlated thereto, and relative apparatus

1. A method to determine a speed of sedimentation, viscosity, elasticity and density of blood, said method being carried out by detecting a development over time of an optical density, or an absorbance, of a sample of blood, said sample being sent in the form of a flow inside a capillary container (12), said detection being made in correspondence with any point along the length of said capillary container (12) and the optical density or the absorbance acquired being processed to obtain said speed of sedimentation, viscosity, elasticity and density wherein the method instantly interrupts the flow of the blood sample flowing inside said capillary container (12), in order to determine a compaction of red cells inside said blood sample and their consequent sedimentation, and makes said detection substantially simultaneously with said instant interruption.
