Abstract
An instrument for measuring coagulation parameters is provided in which plasma and at least one reagent are mixed by spinning in a cuvette with transparent windows and in which measurement is then made of scatter by the mixture of the energy of a light beam sent into the mixture. Upon spin, the plasma components and reagent are displaced into the chamber, thus determining the initiation of the presence of the mixture in which the clot forms, and a photodetecting unit senses the change in the energy of the scattered light, caused by clot formation.
