WebDec 1, 2024 · Prolongation of both PT and aPTT indicates a problem with a common pathway factor (fibrinogen, factor II, factor V, and factor X). Noncorrection on mixing studies indicates the presence of an inhibitor. Because only factor V has decreased activity, this patient has a specific factor V inhibitor. Historically, such inhibitors have resulted from ... WebActivated partial thromboplastin time (PTT) is a routine coagulation screening test that is sensitive to declines of activities of factors II, V, VIII, IX, XI, XII, kallikrein, high-molecular-weight kininogen, and reduced concentration of fibrinogen. It is also utilized to monitor heparin therapy and some other anticoagulant drugs.

WebAug 8, 2024 · Partial thromboplastin time (PTT) is the time it takes for a patient's blood to form a clot as measured in seconds. It is used to measure the activity of the intrinsic pathway of the clotting cascade.

A typical aPTT value is 30 to 40 seconds. If you get the test because you’re taking heparin, you’d want your PTT results to be more like 120 to 140 seconds, and your aPTT to be 60 to 80 seconds. If your number is higher than normal, it could mean several things, from a bleeding disorder to liver disease.
