Laboratory criteria for diagnosisīiologic: The criteria for diagnosis of a long-acting anticoagulant is the presence of one of the following factors: Coagulopathy might manifest as epistaxis, gingival bleeding, hematemesis, hematuria, hematochezia, menometrorrhagia, ecchymosis, petechial hemorrhages, intracranial hemorrhages, or bleeding that is disproportionate to the level of the injury (1-3).

After a substantial ingestion of a long-acting anticoagulant, clinical signs of coagulopathy typically occur within 24-72 hours.

After an acute unintentional ingestion of a long-acting anticoagulant, the majority of patients are entirely asymptomatic.
