Part Descriptions

LP15957-1   Coagulation surface induced
Coagulation surface induced (aPTT) is the evaluation of intrinsic coagulation system and is useful in monitoring heparin therapy; aid in screening for the following: presence of classical hemophilia A, and B; Christmas disease; congenital deficiencies of factors II, V, VIII, IX, X, XI, and XII; presence of dysfibrinogenemia; disseminated intravascular coagulation; liver failure;congenital hypofibrinogenemia; vitamin K deficiency; congenital deficiency of Fitzgerald factor; congenital deficiency of prekallikrein; circulatory anticoagulant when heparin is given for treatment or prevention of thromboembolism.

LP15957-1   Coagulation surface induced
The partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT or APTT) is a performance indicator measuring the efficacy of both the "intrinsic" (now referred to as the contact activation pathway) and the common coagulation pathways. Apart from detecting abnormalities in blood clotting, it is also used to monitor the treatment effects with heparin, a major anticoagulant. It is used in conjunction with the prothrombin time (PT) which measures the extrinsic pathway. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
