THE usual way of determining time of coagulation, which is of diagnostic importance, is to observe clot formation. There has been no report of any way of measuring coagulation time with an accuracy of a few seconds. We report here our observations of the coagulation of human plasma, using a simple, sensitive and reproducible photoelectric device developed in this laboratory to study blood coagulation. The idea originated from a suggestion of Born1.
