The formation of human blood sediment by means of optical method was studied. Light was transmitted through a layer of blood. The temporal changes of the transmitted light intensity along the sample were measured. Samples of blood from a healthy donor were investigated. The optical method permits us to distinguish three phases of the blood sediment. At the top of the container the well-known supernatant plasma layer creates. In the sediment of the red blood two phases were distinguished. The rouleau formation phase and the phase of demixed blood were found. The two phases are separated by the moving boundary. The kinetics of this boundary was determined. The optical data admit to a hypothesis about the physical phenomena of the sedimentation process. The spinodal decomposition may be one of the mechanisms of the blood sediment formation.
