Point-of-Care Testing of Coagulation in Patients Treated With Direct Oral Anticoagulants 2

Completed
Conditions
Anticoagulation With Direct Oral Anticoagulants
Registration Number
NCT02371070
Lead Sponsor
University Hospital Tuebingen
Brief Summary

The investigators study aims to test the correlation between the Hemochron Signature point-of-care testing (POCT) device (ITC, USA) and low plasma levels of all three currently approved direct oral anticoagulants (DOAC; rivaroxaban, apixaban and dabigatran) and to determine the diagnostic accuracy of POCT to rule out or detect relevant levels of DOAC in real-life stroke patients.
