    The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...

    003436. [ edit on Wikidata] Liver function tests ( LFTs or LFs ), also referred to as a hepatic panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin, bilirubin (direct and indirect), and others.

  5. Mixing study - Wikipedia

    en.wikipedia.org/wiki/Mixing_study

    Mixing studies are screening tests widely performed in coagulation laboratories. 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 ...

    en.wikipedia.org/wiki/Partial_thromboplastin_time

    The partial thromboplastin time ( PTT ), also known as the activated partial thromboplastin time ( aPTT or APTT ), is a blood test that characterizes coagulation of the blood. A historical name for this measure is the kaolin-cephalin clotting time ( KCCT ), [1] reflecting kaolin and cephalin as materials historically used in the test.
