Background: The first purpose of this study was to determine whether a measurement of the level of direct oral anticoagulants (DOACs) was possible with heparin-calibrated chromogenic anti-factor Xa activity (AXA). The second purpose of this study was to evaluate whethe...

Methods: In the derivation cohort then in the validation cohort, via receiver operatingcharacteristics (ROC) curve analysis, we evaluated the ability of heparin anti-Xaassay to detect levels of factor-Xa inhibitors above or below the abovementioned safety thresholds recommended for an invasive ...
This BIOPHEN™ ANTI-IIa (2 Stages Heparin Assay) kit is a two-stage chromogenic assay for measuring the activity of heparins (UFH or LMWH), in manual or automatic method. This method is proposed only to test heparin in human citrated plasma, or in purified solution. This kit is for ...
Several heparin preparations have been assayed using the Denson and Bonnar anti-Xa assay. The heat defibrination step involved in this assay has been shown to introduce discrepancies into the results, due mainly to co-precipitation of the heparin with fibrinogen. The amount of heparin lost is de...
