5964-2Prothrombin time (PT) in Blood by Coagulation assayActive

Part Description

LP16870-5   Coagulation tissue factor induced
The prothrombin time (PT) and its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) are measures of the extrinsic pathway of coagulation. They are used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage and vitamin K status. The reference range for prothrombin time is usually around 12-15 seconds; the normal range for the INR is 0.8-1.2. It is used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway. PT is sometimes used as the third screening test in the lupus anticoagulant testing algorithm and is included in the LOINC LA aPTT & dRVVT & PT panel.
