A reference range study was conducted for the QPlus cartridge by collecting whole blood samples from 129 healthy donors across three sites. The data were evaluated as recommended in EP28-A3c “Defining, Establishing and Verifying Reference Intervals in the Clinical Laboratory; Approved Guideline – Third Edition” CLSI, October 2010. The reference range for the Clot Stability to Lysis (CSL) parameter was similarly determined in a study of 43 healthy adult donors conducted at two sites in the US with the QStat Cartridge. The reference ranges determined from these studies are expressed as the central 95% confidence interval of the mean. It is recommended that each hospital/laboratory confirm these ranges or establish its own expected values for the populations it serves.
Sonic Estimation of Elasticity via Resonance (SEER) Sonorheometry is an ultrasound-based technology that measures the shear modulus of whole blood during coagulation and clot lysis.

Cartridge based closed system; closed tube sampling.

Introducing our new fibrinogen POC solution

qLabs® FIB
Fibrinogen Monitoring System
Fibrinogen plays a critical role in the haemostatic process and has been identified as the first factor to reach critically low levels during active bleeding such as trauma and PPH.
Stago is proud to introduce the new qLabs FIB, a point-of-care device that measures fibrinogen levels within 1 to 10 minutes. This enables rapid, goal-directed therapy, with early administration of fibrinogen supplementation in the management of critical bleeds.
Features and Specs
Quantification of functional fibrinogen Clot-based fibrinogen measurement correlated to Clause fibrinogen method
Sample Type Venous whole blood in standard coagulation citrated tube (blue cap, 3.2% (0.109 M) sodium citrate)
Sample Volume 15 µL
Precision CV ≤ 7.0%
Hematocrit Range 20% to 60%
Shelf Life at Room Temparature 24 months
Features and Specs
Designation Ref.# Packaging
qLabs® FIB meter Q-3 Plus Unit
eStation II docking station MBI92 Unit
qLabs® FIB Test strips QS-18 Pro 24 strips/box
qLabs® FIB Controls level 1 QS-18-CLN 4 x 1 mL
qLabs® FIB Controls level 2 QS-18-CLP 4 x 1 mL
Indications: The Quantra Hemostasis System is comprised of the Quantra Hemostasis Analyzer, QPlus Cartridge, QStat Cartridge, Quantra Quality Controls (Level 1 and Level 2), Quantra Cleaning Cartridge, and Quantra Desktop Remote Viewer (QDRV) Software.
The QPlus Cartridge 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.
The QStat Cartridge is indicated for the evaluation of blood coagulation and clot lysis in patients age 18 years and older to assess possible hypocoagulable and hypercoagulable conditions in trauma and liver transplantation procedures

Results obtained with the Quantra System should not be the sole basis for patient diagnosis.

Rx Only.
