Breaking New Ground in Bleeding Management with Point-of-Care Viscoelastic Testing

Manage bleeding in critical care setting

Quantra POC analyser helps reduce the use of unnecessary blood products

The Quantra point-of-care haemostasis analyser is designed to aid in the management of bleeding in the critical care setting.  It delivers actionable results within 15 minutes.  Easy-to-use and interpret, this POC system helps you choose the right treatment in the right time.

Acute perioperative situations demand fast action on whether to transfuse critically bleeding patients. That’s the risk with all major surgery – from trauma, organ transplants, orthopaedics to cardiothoracic procedures. In cardiac surgery, post-surgical bleeding occurs in up to 20% of cases, while the trauma of post-partum haemorrhage is the leading cause of maternal mortality worldwide.


Designed for Point-of- Care

Simple to use - three-push workflow for busy perioperative settings


Intuitive by Design

Results are displayed numerically on dials or easy-to-interpret curves


Rapid Results

Takes less than 60 seconds to set up, with clinical data delivered within minutes

Appearing as numbers on the dial screen with no deciphering needed

Take a look at ‘your patient is bleeding’ and see how quickly the life-saving information appears on the Quantra screen. The fully closed, cartridge-based system starts providing significant data within five minutes with the full picture, including clotting time and the quality of any formed clot, ready to view within 15 minutes.

The Quantra cartridge-based viscoelastic testing system may be a new name to you – but you’ll probably know our global parent company, Diagnostica Stago. We’re recognised worldwide for our expertise in haemostasis and thrombosis, supporting your clinical laboratory.

Because of Quantra’s speed, ease of use and precision, it is already being trialled by leading hospitals in the UK and Europe.  Its performance has convinced several clinical teams to integrate it into their routine surgical protocols. 

Quantra’s high precision, generally strong correlation to standard laboratory assays and good concordance with the clinical presentation are demonstrated in numerous clinical studies. Download below our bibliography.
Recent findings confirmed its high negative predictive value for thrombocytopenia, identifying potential cut-off values for the FCS (fibrinogen contribution to clot stiffness) and PCS (platelet contribution to clot stiffness) parameters. The study indicates these values could be safely used in place of (or alongside) lab-based fibrinogen and platelet thresholds – for guiding transfusion decisions.

For Cardiovascular Surgery and Major Orthopaedic Surgery

Quantra is currently the only VET instrument that directly outputs both fibrinogen (FCS) and platelet contributions to clot stiffness (PCS). This helps you quickly determine if  these are required without having to calculate them manually – speeding up decision-making.

Unlike some other systems, you can obtain QPlus clot stiffness parameters while your patient is on bypass

Six QPlus parameters

Results time


Clot times with/without heparinase (CT & CTH), clot stiffness (CS), fibrinogen contribution to clot stiffness (FCS), clot time ratio (CTR), & platelet contribution to clot stiffness (PCS)

For Trauma & Critical Care, Liver transplants and Obstetrics

Studies confirm that QStat can also assess fibrinolysis in trauma patients. CSL is a calculated functional parameter, indicating the reduction of clot stiffness that is likely to be due to fibrinolysis.  By directly comparing changes in clot stiffness (with & without TXA), it automatically corrects for clot retraction due to interaction between platelets, fibrinogen and the POC device.
