Our results show that dabigatran (Hyphen and Technoclone) and rivaroxaban (Stago) calibrators tend to overestimate the APTT but are similar to patient samples for PT. A cut-off DOAC level of 50 ng/mL based on results from patient samples within the laboratory can be used as the lower limit which will result in prolongation of APTT for dabigatran (sensitivity 96%, n = 25) and PT for rivaroxaban (sensitivity 97%, n = 29), respectively. Individual laboratories should be familiar with the sensitivity of their coagulation reagents to different DOACs including differences between patient samples versus different commercial drug specific calibrators.]]> Wed 11 Apr 2018 15:02:58 AEST ]]> Safety of anticoagulation in the treatment of venous thromboembolism in patients with haematological malignancies and thrombocytopenia: report of 5 cases and literature review https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29675 Wed 02 Mar 2022 14:26:49 AEDT ]]> A systematic review and meta-analysis comparing anticoagulation versus no anticoagulation and shorter versus longer duration of anticoagulation for treatment of isolated distal deep vein thrombosis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34050 Thu 28 Oct 2021 13:03:25 AEDT ]]>
