VW (von Willebrand) Factor Blood Clotting Test
The VON WILLEBRAND (VW) Factor test measures the level of von Willebrand factor (VWF) in the blood. This protein plays an important role in the blood clotting process by helping platelets stick together and form a clot to stop bleeding.
Von Willebrand factor also helps carry and stabilize Factor VIII, another important protein involved in blood clotting. When the level of this factor is low or not functioning properly, it may lead to a condition called Von Willebrand disease, which is a common inherited bleeding disorder.
People with this condition may experience symptoms such as frequent nosebleeds, easy bruising, prolonged bleeding from cuts, or heavy menstrual bleeding. Therefore, this test helps doctors evaluate clotting function and diagnose bleeding disorders.
