Clot waveform analysis: Where do we stand in 2017?

Analysis of the optical waveform generated during global coagulation assays, such as activated partial thromboplastin time and prothrombin time, can provide much precious information on the global coagulation state of the plasma sample tested, in addition to a single clotting time. Many studies have been published concerning patient diagnosis and management in haemophilia A, and in the early diagnosis and prognosis of disseminated intravascular coagulation and sepsis. However, many other works have also been published on further potential clinical applications such as lupus anticoagulant diagnosis and anticoagulant monitoring. Altogether, these publications have demonstrated the ability for clot waveform analysis (CWA) to improve patient management, especially as this tool is inexpensive, rapid and readily available on coagulation analysers with optical detection systems. By an extensive review of the literature related to studies performed on CWA, this publication aims at providing a review of current knowledge in this specific field, ranging from research data to potential clinical applications and future trends.
