Summary

This study is testing a new device that mimics a blood vessel to evaluate how well a person's blood clots under realistic flow conditions. Researchers will compare results from healthy donors, patients with von Willebrand disease, and those on antiplatelet drugs. The goal is to see if this test can more accurately identify bleeding risk than current methods.
