2. Prothrombin time - Wikipedia

   en.wikipedia.org/wiki/Prothrombin_time

   The prothrombin time (PT) – along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation. This blood test is also called protime INR and PT/INR.

3. Liver function tests - Wikipedia

   en.wikipedia.org/wiki/Liver_function_tests

   Prothrombin time (PT) and its derived measures of prothrombin ratio (PR) and INR are measures of the extrinsic pathway of coagulation. This test is also called "ProTime INR" and "INR PT". They are used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage, and vitamin K status. [16]

4. INR self-monitoring - Wikipedia

   en.wikipedia.org/wiki/INR_self-monitoring

   The study was a prospective, randomized, non-blinded trial for which the patients were randomized into two groups, (i) weekly INR self-testing and (ii) monthly INR clinic-testing, using a stratified method of adaptive-allocation that was determined according to the duration of anti-coagulation and the indication for Warfarin. Although the study ...

5. Mixing study - Wikipedia

   en.wikipedia.org/wiki/Mixing_study

   The basic purpose of these tests is to determine the cause of prolongation of Prothrombin Time (PT), Partial Thromboplastin Time, or sometimes of thrombin time (TT). Mixing studies take advantage of the fact that factor levels that are 50 percent of normal should give a normal Prothrombin time (PT) or Partial thromboplastin time (PTT) result. [2]

6. Clotting time - Wikipedia

   en.wikipedia.org/wiki/Clotting_time

   Clotting time is a general term for the time required for a sample of blood to form a clot, or, in medical terms, coagulate.The term "clotting time" is often used when referring to tests such as the prothrombin time (PT), activated partial thromboplastin time (aPTT or PTT), activated clotting time (ACT), thrombin time (TT), or Reptilase time.

7. Coagulation testing - Wikipedia

   en.wikipedia.org/wiki/Coagulation_testing

   Prothrombin time test (or prothrombin test, INR, PT) – velocity of passage of the extrinsic blood coagulation pathway Poor plasma; Not sensitive to deficiency of intrinsic coagulation pathway factors; Highly specialized methods to reveal the alteration in concentration of separate factors.
