Charlottesville, VA, January 19, 2021 – HemoSonics welcomes the January 14th guidance of the US Food and Drug Administration (FDA) that broadens the use of viscoelastic coagulation analyzers for hospital patient healthcare settings in response to COVID-19. The FDA guidance is intended, for the duration of the COVID-19 public health emergency, to expand the availability of coagulation systems for measurement of whole blood viscoelastic properties to assess hemostasis.1

HemoSonics’s flagship product, the Quantra Hemostasis Analyzer, with its QPlus® cartridge, represents the only viscoelastic coagulation testing (VET) system specifically designed and optimized for rapid and easy operation in point-of-care (POC) settings, such as operating rooms, Emergency Departments, or intensive care units. The Quantra system’s innovative closed-cartridge design requires no open-tube blood manipulation after sample collection. The Quantra system is FDA cleared (de novo) for POC use, which may help to minimize the flow of traffic with sample transporters and/or operators in and out of units designated for the care of COVID-19 patients.

“The Quantra System’s intuitive operation and easy-to-interpret Dials display may help streamline what is otherwise a complex process of coagulation testing,” said Bob Roda, CEO of HemoSonics. “The QPlus cartridge provides multiple whole blood coagulation parameters within 15 minutes or less, helping clinicians to make quicker, more informed treatment decisions that support better patient outcomes.” 

Hypercoagulability, an abnormally increased risk for blood clotting, has been observed in patients with COVID-19.2 Clinical reports have shown that in patients with severe COVID-19 infection, blood clotting abnormalities are likely triggered by the acute inflammatory response.3-7

HemoSonics has advocated for the use of viscoelastic whole blood testing as a tool in the diagnosis and management of COVID-19 patients, consistent with its mission to provide efficient, easy-to-use tools that improve patient care.

Since the onset of the global pandemic, HemoSonics has supported several clinical sites in Europe and the US in their quest to understand the potential utility of the Quantra system for the evaluation of coagulation status in COVID-19 patients at the POC setting:7

“The Quantra is the only device on which we can operate safely without needing specialized rooms and a biohazard cabinet.”

The Quantra system’s innovative ultrasound technology, proprietary closed-cartridge design, unparalleled ease of use, and ease of interpretation make it uniquely suited for use in critical or emergency care settings with COVID-19 patients.
