Thank you for visiting HemoSonics! We present the Quantra® Hemostasis Analyzer – the next-generation, RAPID, closed-cartridge viscoelastic (VET) assay optimized for Point-of-Care use, and its initial QPlus® cartridge indicated for use in perioperative patients undergoing cardiovascular or major orthopedic surgeries.

When a patient is bleeding in OR or ICU, goal-directed bleeding management and optimized use of blood products are of utmost importance. Whole-blood viscoelastic testing at the point of care has been shown to improve patient outcomes and reduce blood products usage and wastage. The Quantra Hemostasis Analyzer is the next-generation, closed-cartridge viscoelastic hemostatic assay optimized for point-of-care use in perioperative patients:

  • Ease of use: Simple, intuitive, and safe POC workflow from sample collection to cartridge disposal.
  • Ease of interpretation: Innovative “dials” display option for expedited interpretation training.
  • Rapid actionable results: Whole blood coagulation information within 15 minutes or less.
  • Hassle-free validation, training, and IQCP development facilitated by HemoSonics.
  • No fuss maintenance and infrequent external QC recommendation.

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

Product Availability and Indications

USA: The Quantra QPlus® System is composed of the Quantra Hemostasis Analyzer, QPlus Cartridge, and Quantra Quality Controls Level 1 and 2. The Quantra QPlus System is intended for in vitro diagnostic use. The Quantra Hemostasis Analyzer uses Sonic Estimation of Elasticity via Resonance (SEER) Sonorheometry, an ultrasound-based technology, to measure the shear modulus of whole blood during coagulation. The QPlus Cartridge is a multi-channel cartridge that provides semi-quantitative indications of the coagulation state of a 3.2% citrated venous whole blood sample. The QPlus Cartridge includes tests to assess coagulation characteristics via the intrinsic pathway, via the extrinsic pathway, and includes tests with a heparin neutralizer. The system is intended to be used by trained professionals at the point-of-care and in clinical laboratories to evaluate the viscoelastic properties of whole blood by means of the following functional parameters: Clot Time (CT), Clot Time with Heparinase (CTH), Clot Stiffness (CS), Fibrinogen Contribution to Clot Stiffness (FCS), Platelet Contribution to Clot Stiffness (PCS) and Clot Time Ratio (CTR).The Quantra QPlus System is indicated for the evaluation of blood coagulation in perioperative patients age 18 years and older to assess possible hypocoagulable and hypercoagulable conditions in cardiovascular or major orthopedic surgeries before, during, and following the procedure.

Results obtained with the Quantra QPlus System should not be the sole basis for patient diagnosis. Rx Only. The Quantra QPlus System has not been evaluated to guide blood product use or use of medication. Please consult the Quantra User Manual and/or cartridge Instructions for Use for complete information.

OUS: The Quantra Hemostasis Analyzer, QPlus and QStat® Cartridges, and their respective Quality Controls Level 1 and 2 are CE Marked for use with patients 18 years of age or older where an evaluation of their blood coagulation properties is desired. Coagulation evaluations are commonly used to assess clinical conditions in surgery (e.g. cardiovascular and trauma surgeries) to assess risk of hemorrhage and thrombosis before, during, and following the procedure. Product availability is subject to fulfillment of regulatory requirements in each market.
