WebbNormal ranges for the PT, aPTT, and anti-factor Xa activity vary among laboratories and should be reported from the testing laboratory along with the patient result. Refer to the UpToDate topic on coagulation testing for details. PT: prothrombin time; aPTT: activated partial thromboplastin time; LMW heparin: low molecular weight heparin. Webb1 juni 2024 · The optimal therapeutic aPTT range for treating acute venous thromboembolism should be defined as the aPTT range (in seconds) that correlates with a plasma activity level of unfractionated heparin of 0.3 to 0.7 U/mL based on a chromogenic anti-Xa assay, or 0.2 to 0.4 U/ mL based on a protamine titration assay. 32,34–36
