A Ristocetin Cofactor test helps evaluate the functioning of a protein that helps blood to clot.
The ristocetin cofactor test is the primary assay used to diagnose von Willebrand disease as it measures plasma von Willebrand factor activity.
The ristocetin cofactor test is usually performed together with the von Willebrand factor antigen and the factor VIII activity assay, forming the von Willebrand disease profile.
Von Willebrand factor is involved in the early stages of blood clotting. As the platelets gather at the injury site, vWF acts like glue, helping them stick together to stop the bleeding.
