Ristocetin Cofactor

The Ristocetin Cofactor test is a diagnostic tool used primarily to detect abnormalities in the interaction between your blood platelets and a protein called von Willebrand Factor (vWF). This protein plays a significant role in the blood clotting process. When a blood vessel is damaged and bleeding occurs, vWF helps platelets to stick together and form a clot to stop the bleeding.


  • Test NameRistocetin Cofactor
  • Sample TypeBlood
  • Preparations RequiredNo special preparation is needed for the test. However, make sure to inform your healthcare provider about any medications you're taking, as certain drugs can affect the test results.

In certain conditions, like von Willebrand disease (vWD), the levels or function of vWF may be abnormal, leading to a higher risk of bleeding or clotting. The Ristocetin Cofactor test helps assess vWF activity, aiding in the diagnosis and monitoring of vWD and similar conditions.
