A 25-year evaluation of direct local international normalized ratio calibration of the Owren type prothrombin time method in Sweden
There is good agreement among PT measurements across Swedish laboratories, with no significant differences in reagents. The user-friendly, unique calibration procedure, including the preparation of certified plasmas, improved the performance of national PT measurements and has been shown to remain stable over decades.
