Summary

The Quantra(r) hemostasis analyzer (Stago) is a recent addition to the family of global hemostasis tests. It uses ultrasound-based technology to characterize the viscoelastic properties of a whole blood sample during coagulation. The Qplus(r) cartridge consists of independent channels, each containing different reagents that provide parallel measurements of 6 parameters. This global test takes into account cellular elements such as platelets and red blood cells in clot formation, and also explores fibrinolysis. In addition, this test is of particular interest in delocalized biology, i.e. at the patient's bedside, and avoids the time-consuming laboratory centrifugation stage required for routine analyzers. In practice, this test has been developed to monitor haemostasis in patients who may present with a range of coagulopathies of various etiologies, but also in the management of haemorrhagic patients, in order to adapt the administration of blood products in particular. The Quantra (r) analyzer could therefore be of interest since it could be deployed in overseas operations to manage war casualties. Recent studies (EACTAIC-ICCVA congress, October 2021) have shown that there is a good correlation between anti-Xa activity and the CTR (coagulation time ratio) parameter of the Quantra cartridge Qplus (TM), suggesting that this automated system could be used to manage anticoagulant therapy.
