Stago Launches Products for Measurement of Rivaroxaban


We would like to announce that Diagnostica Stago, Inc. offers the STA® – Rivaroxaban Calibrator and Controls, which are highly specific, automation-ready products for determining the rivaroxaban concentration in plasma when used in conjunction with the STA® - Liquid Anti-Xa assay.  This method was shown to have favorable performance with respect to its linearity and coefficient of variation (CV) in a recent publication.1 


Rivaroxaban (Xarelto®), a synthetically derived drug from Janssen Pharmaceuticals and Bayer Healthcare, inhibits the blood coagulation cascade by its inhibitory action on coagulation factor Xa, resulting in inhibition of fibrin clot formation.2


The STA® – Rivaroxaban Calibrator (catalog # 00704US) and Control (catalog # 00706US) products contain two levels of control at the low and high end of the calibrator range.  Utilization of STA® – Rivaroxaban Calibrator and Controls ensures high specificity and precision for rivaroxaban determination. 


The rivaroxaban controls and calibrators are labeled for research use only, and are not for use in diagnostic procedures in the United States and Canada.
