Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 Quantra QPlus Cartridge was developed to monitor hemostasis during major surgical procedures in adult patients. The cartridge consists of four independent channels each containing different sets of reagents, which provide four measurements performed in parallel yielding six parameters that depict the functional status of a patient's coagulation system.

This single-site, prospective, observational study will evaluate the performance of the Quantra System as compared to standard coagulation tests and comparable measures determined using TEG in patients taking antiplatelet medication that are scheduled to undergo cardiac surgery.
