Clot formation [Time] in Blood by Thromboelastography

Active

Term Description

Tests such as the prothrombin time (PT) and activated prothromin time (aPTT) can predict bleeding or be used for haemostasis management, but it is difficult to determine which part of the intrinsic or extrinsic pathway is disrupted in an individual. Since these tests are performed on platelet-poor plasma, they do not provide a true representation of the physiological clotting process so they do no provide adequate information on either clot formation over time or fibrinolysis. (Young et al, 2013).
Clotting time (CT) is the time for a clot to reach an amplitude of 2 mm. Clot formation time (CFT) is the time for clot firmness to incease from 2mm (CT) to 20 mm. A prolonged CFT is usually caused by poor platelet function, low platelet count, fibrin polymerization disorders or fibrinogen deficiency. Higher concentrations of heparin can also prolong CFT in the INTEM assay, but not in HEPTEM, EXTEM, FIBTEM or APTEM. A low CFT indicates hypercoagulability. PMID: 27264484

LP69276-1 Thromboelastography
Thromboelastography (TEG) is a viscoelastic test of hemostasis. In TEG, whole blood is added to a cup in which a pin is suspended, the cup is rotated, and as the clot forms, the rotational force is transferred to the pin. The torsion of the pin is transformed into a graphic record of the physical shape of a clot during fibrin formation and lysis. TEG can provide information about the status of coagulation factors, platelet function and fibrinolysis in whole blood. TEG is primarily used for assessment of hemostasis after cardiopulmonary bypass, during liver transplant surgery, or hemorrhaging episodes. TEG parameters are also used as part of the guiding algorithms for plasma, platelet and cryoprecipitate transfusions. Copyright Copyright © 1995-2009 Source: Mayo Medical Laboratories
