Question: what is anti xa monitoring?
Answer: The anti–factor Xa assay is designed to measure plasma heparin (UH and LMWH) levels and to monitor anticoagulant therapy. Heparin is a mixture of negatively charged glycosaminoglycans (sulfated mucopolysaccharides) that have anticoagulant properties due to their interaction with the natural anticoagulant antithrombin.
