WebJuly 2024—With the introduction of direct oral anticoagulants (DOAC) there is a paradigm shift in the use and understanding of screening coagulation tests to determine a patient’s bleeding risk. In patients on DOAC therapy, clinicians cannot rely on normal activated partial thromboplastin time (APTT) and prothrombin time (PT) results to reflect the patient’s … WebSep 27, 2024 · Introduction.
