    An evaluation of a photoelectric clot timer, the Lancer Coagulyzer, in measuring the one-stage prothrombin time has been carried out. The machine is considered to provide reliable results on correctly taken samples without interference by plasma bilirubin, only rarely failing to detect clotting in turbid plasma using a wide range of thromboplastins. The apparatus is useful where there is a sufficient number of samples to be tested.
