VIII:vWF plays a crucial role in platelet adhesion and aggregation to the subendothelium. The platelet response to the aggregation by ristocetin indicates the function of VIII:vWF in vivo by measuring the binding of giant platelets and/or agglutination of normal size platelets in the presence of ristocetin.
