The reference range for prothrombin time depends on the analytical method used, but is usually around 12â13 seconds (results should always be interpreted using the reference range from the laboratory that performed the test), and the INR in absence of anticoagulation therapy is 0.8-1.2.aboratory measurement [edit].
