WebThe activated partial thromboplastin time (APTT or aPTT) is a coagulation test used to evaluate low-dose heparin therapy and test for the function of hemostasis’ intrinsic and normal pathway. The reagent used to perform the APTT is partial thromboplastin, which is the lipid portion of thromboplastin in the tissue. WebPTT was useful in detecting intrinsic factors abnormalities, but it was relatively insensitive to the effect of heparin. But APTT was sensitive to the heparin effect. The APTT was very sensitive to coagulation factors deficiency within the intrinsic pathway before the prothrombin was converted to thrombin. Detect the Intrinsic thromboplastin ...
