Brief Summary

The anti-factor Xa (anti-Xa) assay is a functional assay that facilitates the measurement of antithrombin (AT)-catalyzed inhibition of factor Xa by unfractionated heparin (UFH) and direct inhibition of factor Xa by low-molecular-weight heparin (LMWH). As a result, Anti-factor Xa level reflect the in situ pharmacological activity of LMWH. 0.2 to 0.5 units/ml has been considered to be the desired level for prevention of VTE. Although this method was available since the 1970s, their cost was viewed to prohibit their broad use until recently. Previous studies determined the safety and effectiveness of fixed dose prophylactic regiments via clinical outcomes. This strategy has several shortcomings. The current study was there for devised to examine in vivo activity of LMWH in patients receiving a fixed dose prophylactic regimen, in order to assess the effectiveness of this method.
