Assessing thrombophilia with activated charcoal for patients on DOACs

Thrombophilia Assessment Under Direct Oral Anticoagulants (DOAC): Efficacy of Activated Charcoal

Observational University Hospital, Strasbourg, France · NCT06171984

This study is testing if activated charcoal can help improve blood tests for people on blood thinners like Apixaban and Rivaroxaban by making it easier to check for clotting disorders.

What this trial studies

This observational study evaluates the effectiveness of activated charcoal in adsorbing direct oral anticoagulants (DOACs) like Apixaban and Rivaroxaban to facilitate thrombophilia testing. It aims to address the challenges posed by DOACs on coagulation tests, which can interfere with the assessment of conditions like protein S deficiency and lupus anticoagulants. By reusing blood samples already analyzed in the laboratory, the study seeks to improve the accuracy of thrombophilia workups for patients on these medications.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have had their blood samples analyzed as part of routine care.

Not a fit: Patients with insufficient blood samples will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the ability to diagnose thrombophilia in patients taking DOACs, leading to better management of their condition.

How similar studies have performed: While the use of activated charcoal for this purpose is novel, recent studies have indicated its potential effectiveness in improving coagulation testing accuracy in patients on DOACs.
