The Quantra® System is composed of the Quantra Hemostasis Analyzer, QPlus Cartridge, QStat Cartridge, and Quantra Quality Controls Level 1 and 2. The Quantra 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 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.
The QPlus Cartridge is a multi-channel cartridge that provides semi-quantitative indications of the coagulation state of a 3.2% citrated venous or arterial 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 QPlus Cartridge is indicated for use in cardiovascular or major orthopedic surgeries before, during, and following the procedure.
The QStat Cartridge is a multi-channel cartridge that provides semi-quantitative indications of the coagulation and clot lysis state of a 3.2% citrated venous whole blood sample. The QStat Cartridge includes tests to assess coagulation characteristics via the intrinsic pathway, via the extrinsic pathway, and includes a test with tranexamic acid to evaluate clot lysis characteristics. The QStat Cartridge is indicated for use in trauma and liver transplantation procedures.
The Quantra System is indicated for the evaluation of blood coagulation in perioperative patients age 18 years and older to assess possible hypocoagulable and hypercoagulable conditions. Results obtained with the Quantra System should not be the sole basis for patient diagnosis.
Indications for use as stated in the FDA summary.
