What is VON WILLEBRAND RISTOCETIN COFACTOR (VWF) ACTIVITY?

The Von Willebrand Ristocetin Cofactor Activity test measures how well your Von Willebrand factor protein is functioning. It assesses the ability of VWF to bind to platelets, a critical step in the blood clotting process, using a substance called ristocetin.

Why is this test important?

This test is crucial for diagnosing and classifying different types of Von Willebrand Disease (VWD) by evaluating the functional activity of VWF. Low activity indicates impaired clotting, leading to bleeding tendencies, even if the VWF antigen levels are normal.

How to Prepare

No special preparation required. Inform your doctor about any medications, especially blood thinners, you are taking.
