Activated partial thromboplastin time (APTT)

Bleeding time

Prothrombin time (PT)

Hemoglobin (Hgb)

Answer and Explanation

The Correct Answer is C

warfarin inhibits vitamin K epoxide reductase interfering with the synthesis of vitamin K dependent clotting factors (II, VII, IX, and X). This prolongs the prothrombin time, expressed in the form of INR international normalized ratio. Monitoring of INR helps to ensure that the prescribed dosages are within the therapeutic levels without increasing the risk of bleeding. The target INR range is between 2.5 and 3.5.
A. Used to monitor heparin therapy

B, D- not used for monitoring
