Also known as: Activated Partial Thromboplastin Time; aPTT; APTT. Formal name: Partial Thromboplastin Time. Related tests: PT and INR; Fibrinogen; D-dimer; Thrombin Time; Lupus Anticoagulant Testing; ACT; Coagulation Factors; Platelet Count; Heparin Anti-Xa; von Willebrand Factor; Antiphospholipid Antibodies.
When an initial PTT is prolonged, a second PTT test is performed by mixing the person's plasma with pooled normal plasma (a collection of plasma from a number of normal donors). If the PTT time returns to normal (corrects), it suggests a deficiency of one or more of the coagulation factors in the person's plasma. If the time remains prolonged, then the problem may be due to the presence of an abnormal specific factor inhibitor (autoantibody) or nonspecific lupus anticoagulant.
