Abstract

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.
