Tem Innovations GmbH 555201 ROTEM®

The ROTEM sigma is an in vitro diagnostic (IVD) whole blood hemostasis system intended for use in the evaluation of coagulopathies in Point of Care (POC) or laboratory settings. It uses rotational thromboelastometry to provide semiquantitative information about the coagulation state of a blood sample. The ROTEM sigma system records the kinetic changes in a sample of 3.2% citrated whole blood during clot formation, as well as when the sample clot retracts and/or lyses.Several parameters are measured and reported for this purpose. The graphical presentation reflects the various physiological results, which describe the interaction between coagulation factors and inhibitors, fibrinogen, platelets, and the fibrinolysis system. Additionally, the effect of certain drugs influencing hemostasis, in particular some anticoagulants (e.g. heparin), can be detected.
