What should PTT be when on heparin?

The aPTT is considered a more sensitive version of the PTT and is used to monitor the patient’s response to heparin therapy. The reference range of the aPTT is 30-40 seconds. The reference range of the PTT is 60-70 seconds. PTT: More than 100 seconds (signifies spontaneous bleeding)Click to see full answer. Thereof, what should aPTT be on Heparin?The 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.Secondly, why do you monitor PTT with heparin? When very high doses of heparin are used, as may occur during open-heart surgery, the PTT loses its sensitivity; it will not clot. At this intense level of anticoagulation, the activated clotting time (ACT) can be used as a monitoring tool. Also question is, what is the therapeutic PTT for heparin? Based on the goal PTT the dose of heparin can be increased or decreased to achieve the desired effect. While protocols vary from institution to institution, the therapeutic PTT range for heparin is 60 to 100 seconds, with lower intensity dosing in the range of 60 to 80 seconds.What is a normal PTT level?A typical value for a PTT is 60 to 70 seconds. If you get the test because you’re taking heparin, you’d want your PTT results to be more like 120 to 140 seconds, and your aPTT to be 60 to 80 seconds. If your number is higher than normal, it could mean several things, from a bleeding disorder to liver disease.
