WebMar 18, 2015 · The therapeutic range for heparin antifactor Xa activity level was established by identifying the antifactor Xa activity level corresponding to a known therapeutic heparin level of 0.2 to 0.4 IU/mL by protamine sulfate titration assay. The limitation of this method is the variability in the antifactor Xa activity assay. WebJul 13, 2024 · In addition, heparin dosing was lower in the TEG group compared to the aPTT group (12 IU/kg/h vs. 16 IU/kg/h, respectively, p = 0.03) with no increase in thrombotic complications.
