Dabigatran or Ecarin clotting time is a laboratory test to assess the anticoagulant effect of dabigatran. Ecarin, an enzyme, acts as a direct thrombin inhibitor. It is tested as the time taken for clot formation while converting prothrombin to meizothrombin. Healthcare professionals indicate the test for monitoring patients with thromboembolism. Tests assist in adjusting dosage to achieve optimal anticoagulation.
