| | In other words, to be precise in using the only the prothrombin time itself (without any ratios), one would need to adjust the therapeutic range each time these changes occur, even though the changes may be small. | | | There is nothing inherently wrong with using the raw prothrombin time to adjust coumadin therapy. | | | However, laboratories periodically acquire new instruments or change reagent manufacturers...which changes may affect clotting times. |

| | However, the clinical impact of home prothrombin time monitoring is related to improved warfarin management. | | | For example, Beyth and colleagues reported on a study that randomized 325 patients who started warfarin therapy in the hospital to a self-monitoring and management group or a usual care group. | | | As with any monitoring technology, one would ideally like to isolate the contribution of the monitored data itself from the possible impact of increased patient education or contact with health professionals that is typically associated with more intense monitoring. |
