A method involving a one-stage prothrombin time test for determining a blood clotting mechanism

摘要

A one-stage prothrombin assay which measures the exponential rate of thrombin production in thromboplastin- treated, recalcified plasma. A serum reagent reduces the lag time before thrombin production substantially to zero for both normal and abnormal plasma, thus allowing measurements to be made in just a few minutes.
