About
This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the QStat Cartridge in trauma patients and obstetric patients with postpartum hemorrhage.
Full description
The Quantra System is a fully integrated and automated in vitro diagnostic device which uses SEER Sonorheometry, an ultrasound-based technology, to characterize the viscoelastic properties of a whole blood sample during coagulation. The QStat Cartridge was developed to monitor hemostasis in patients that may experience a range of coagulopathies of various etiologies including fibrinolytic defects. This includes the trauma, obstetric hemorrhage and liver transplant populations. The cartridge consists of four independent channels each containing different sets of reagents, which provide four measurements performed in parallel yielding five parameters that depict the functional status of a patient's coagulation system.
This prospective, observational pilot study will evaluate the performance of the Quantra System with the QStat Cartridge as compared to comparable measures using conventional viscoelastic testing methods.
