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.
