Urine test for anticoagulants in stroke patients

Evaluation of a Urin-based Point-of-Care Testing Device for Direct Oral Anticoagulants in Patients With Acute Ischemic or Hemorrhagic Stroke

Observational University of Giessen · NCT06037200

This study is testing a new urine test to quickly find out if stroke patients are taking blood-thinning medications, which could help doctors make better treatment decisions.

What this trial studies

This study aims to evaluate a urine-based point-of-care testing device designed to detect direct oral anticoagulants (DOACs) in patients diagnosed with stroke. It seeks to determine whether this test can quickly identify patients on DOACs and if it offers time advantages over traditional blood-based coagulation assessments. The feasibility of using this device in acute stroke care settings will also be assessed. By improving the identification of anticoagulant use, the study hopes to enhance treatment decisions for stroke patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a clinical diagnosis of ischemic or hemorrhagic stroke who are being treated at the University Hospital Giessen.

Not a fit: Patients with contraindications for intravenous thrombolysis or those requiring immediate endovascular thrombectomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this test could lead to faster and more accurate treatment decisions for stroke patients on anticoagulants.

How similar studies have performed: While the approach of urine-based testing for anticoagulants is relatively novel, similar studies have shown promise in improving patient management in acute care settings.
