Prothrombin time assay (C0033707)

Definition (NCI) A blood clotting measurement that evaluates the extrinsic pathway of coagulation and is expressed in units of time or percent activity.
Definition (MSH) Clotting time of PLASMA recalcified in the presence of excess TISSUE THROMBOPLASTIN. Factors measured are FIBRINOGEN; PROTHROMBIN; FACTOR V; FACTOR VII; and FACTOR X. It is used for monitoring anticoagulant therapy with COUMARINS.
Definition (CSP) clotting time of plasma recalcified in the presence of excess tissue thromboplastin; used for monitoring anticoagulant therapy with coumarins.
Definition (NCI) A measurement of the clotting time of plasma recalcified in the presence of excess tissue thromboplastin; it is a measure of the extrinsic pathway of coagulation. It is used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage and vitamin K status. Factors measured are fibrinogen, prothrombin, and factors V, VII, and X.
