Lupus Anticoagulant and Abnormal Coagulation Tests in Patients with Covid-19

Abstract
Patients with coronavirus disease 2019 (Covid-19) have a profound hypercoagulable state, and complicating venous thrombotic events are common.1-3 Abnormalities in coagulation screening measures, including a prolonged activated partial-thromboplastin time (aPTT), have been reported in patients with Covid-19.4 This finding could be seen as a reason to avoid the use of anticoagulation at both therapeutic and prophylactic doses.
