ABSTRACT:
Method and apparatus to determine the sedimentation of blood. A blood sample is taken, and an anti-coagulant substance is added. The sample is homogenized. The method includes a step of measuring an optical density, or absorbance, of the sample as a function of time and without waiting for the formation of a plasma/corpuscle interface to obtain an optical density measurement. The measurements are carried out at any fixed point of a reading container which contains a micro-volume of blood. The inner diameter of the containing chamber ensures a linear relationship between the optical density and the number of corpuscles present. Finally, the optical density measurement is processsed to obtain a speed of sedimentation.
