Anti-Xa Assay for Heparin Monitoring [Hot Topic]

Proper weight-based administration of unfractionated heparin has been shown to effectively reduce the morbidity and mortality associated with thromboembolic processes. In addition, it's a common medication for extracorporeal anticoagulation. The most common test for monitoring heparin therapy is the activated partial thromboplastin time (aPTT) test. However, this test does not directly measure heparin and is affected by physiologic and analytic variables. Anti-Xa testing offers improvements over aPTT testing for accurate measurement of heparin levels.
