  • Method for determining prothrombin time
    Patent number: 7767459
    Abstract: A method for determining prothrombin time of a plasma or whole blood sample includes measuring prothrombin time for at least two different dilutions for a test sample to determine tmin or INRmin. The prothrombin time for at least two different dilutions for normal plasma is measured to determine tmin or INRmin values for normal plasma. Next, tPivka or INRPivka values are calculated by subtracting the value for normal plasma from the value for the test sample. The Pivka corrected prothrombin time for the test sample is calculated by subtracting tPivka or INRPivka from the prothrombin time measured for the test sample.

  • METHOD FOR DETERMINING PROTHROMBIN TIME
    Publication number: 20090263903
    Abstract: The present invention relates to tests for monitoring oral anticoagulation therapy and hepatocellular carcinoma (HCC). Particularly, the invention provides a method for determining prothrombin time of a plasma or whole blood sample taking account the effect which protein induced by vitamin K absence or antagonists (Pivka) has on clotting time and INR result. The primary object of the invention is to harmonise prothrombin time methods for international normalized ratio (INR) results and measure INRpivka.
