Quizplus · Accepted Answer

The PT and INR are the most appropriate blood tests to monitor the therapeutic range of warfarin (Coumadin) because they directly measure the clotting activity of the coagulation factors affected by this medication. The therapeutic range for warfarin therapy is typically expressed as an INR between 2.0 and 3.0. Monitoring these values regularly can help prevent either harmful bleeding events or the formation of dangerous blood clots.
