FIGURE 3.
Summarizing the effect of direct oral anticoagulants (DOACs) on the various coagulation assays. An original figure highlighting historical data in which the lead author performed in collaboration with the Royal College of Pathologists of Australasia Quality Assurance Program (RCPQAP) 64 , 65 and showing differential effects on the three assays according to type of DOAC. Data shown as comparative activated partial thromboplastin time (aPTT), dilute Russell's viper venom time (dRVVT), and prothrombin time (PT) ratios. In general, a ratio above 1.2 can be considered as “abnormal”
