Could a doctor please explain to me the difference between pt, ptt, and inr?

PT, PTT, INR: PT or prothrombin time and INR or International Normalized Ratio are used to test the anticoagulant effect of warfarin, PTT or partial thromboplastin time is a more general test of adequacy of clotting factors.
