Overview

Despite their usefulness in perioperative and acute care settings, factor-Xa inhibitors-specific assays are scarcely available, contrary to heparin anti-Xa assay. The investigators aimed at assessing whether the widely used heparin anti-Xa assay can quantify the apixaban, rivaroxaban, fondaparinux and danaparoid levels.

Eligibility

Inclusion Criteria :

  • Blood sample from adult patients treated with apixaban or rivaroxaban or danaparoid or fondaparinux

Exclusion Criteria :

  • Patients treated with unfractionated heparin or low molecular weight heparin
