Webb18 mars 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. WebbThe aPTT is the most commonly used test to monitor heparin therapy. The therapeutic goal for a patient being anticoagulated with heparin, is an aPTT approximately 1.5 to 2.5 times the mean normal value. Heparin is most often administered as an initial intravenous bolus followed by a continuous intravenous infusion.
