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 propoerties of a whole blood sample during coagulation. The Quantra QStat Cartridge was developed to monitor hemostasis in the trauma and liver transplant populations which may experience a range of coagulopathies of various etiologies including fibrinolytic defects.~This single-center, prospective, observational stuey will evaluate the performance of the Quantra System with the QStat Cartridge as compared to corresponding measures determined using the TEG 5000.
This study will assess the clinical performance of the Quantra System with the QStat Cartridge in the liver transplant population.
