Clot formation+Clotting time
Active
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
