A patient with a history of deep vein thrombosis (DVT) is prescribed warfarin therapy. Which laboratory test is used to monitor the therapeutic effect of warfarin?

  • A. Activated partial thromboplastin time (aPTT)
  • B. International normalized ratio (INR)
  • C. Platelet count
  • D. D-dimer
Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.
