The PTT test measures the efficacy and functionality of the coagulation cascade; the coagulation cascade is used to produce blood clots when the body suffers an injury, which causes bleeding. The coagulation cascade helps to prevent further bleeding and also facilitates healing. ...

The major determinant of the APTT-based test was FVIII level, followed by FII level. The ETP-based test was influenced most by free protein S and free TFPI levels. In both tests FXa formation plays a major role, as the effect of FVIII and TFPI on the tests seems to be executed via ...
Patients with hemophilia who cannot be corrected by immediate APTT mixing test should be alert to the possibility of high titer of coagulation factor Ⅷ. 凝血因子Ⅷ抑制物阳性血友病患者APTT纠正试验结果分析. 分析凝血因子Ⅷ抑制物阳性血友病患者APTT纠正试验结果,提高APTT纠正试验在凝血因子Ⅷ抑制物筛查中的...
结论 对孕产妇进行凝血四项检测可以帮助医师判断其身体状况以提供重要参考依据，且有助于预防其产后并发症发生，具有较高的临床推广价值。【关键词】孕产妇；凝血四项；检验；应用价值 Discussion on the application value of APTT, Fg, PT, TT test in pregnant and lying-in women Zeng Zhouyu, Hu Li, Guan ...

The activated partial thromboplastin time (aPTT) assay is a laboratory test used to assess the intrinsic coagulation pathway and monitor the effectiveness of anticoagulant therapy. It measures the time it takes for a blood sample to form a clot when certain reagents are added. The aPTT assay prim...
Blood was collected into tubes containing 0.1 volume of 0.106 m trisodium citrate. Plasma was prepared by centrifugation for 10 min at 2000 g at room temperature and stored at −70 °C. APTT‐based APC sensitivity test The sensitivity of the plasma APTT to APC was measured in Le...
