Method to determine the sedimentation of blood, the method being carried out on a sample consisting of blood to which any anti-coagulant substance has been added and which is suitably homogenised, the method including the monitoring of the development of the optical density, or absorbance, of the sample as a function of time and without initial dead times, the monitoring being carried out at any fixed point of a reading container (22) defining a containing chamber of a small inner diameter which contains a micro-volume of blood, the inner diameter of the containing chamber being such as to ensure a linear relationship between the optical density and the number of corpuscles included. Device to determine the sedimentation of blood, which is of a type that comprises at least one means (20) feeding the sample to be analysed, a reading container (22) set in rotation about an axis perpendicular to its plane of positioning, an assembly (25) to emit/monitor electromagnetic radiations which is positioned perpendicular to the plane of positioning of the reading container (22), a means (26) to acquire data and a programming, processing and control assembly (27), the reading container (22) defining a containing chamber having an inner diameter between 0.1 and 2 mm., but advantageously of 1 mm.
