Coagulation
Conditions
Brief summary
This study will establish reference range intervals for the Quantra System, a next-generation diagnostic platform that provides whole blood coagulation testing at the point-of-care.
Detailed 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 Quantra Surgical 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. In this multi-center, prospective, observational study, blood samples will be obtained from healthy adult volunteers to establish a normal reference range for the test parameters measured by the Quantra System.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Reference range intervals for measurement of Clot Time, Heparinase Clot Time, Clot Stiffness, Fibrinogen Contribution and Platelet Contribution on the Quantra System | Baseline, determined from single blood draw | Reference range intervals determined in this study from the analysis of blood samples collected from healthy adults will serve as the initial reference ranges for the Quantra test parameters when the Surgical Cartridge is commercially available. |
