TECHNICAL BULLETIN
PRODUCT DETAILS
Ristocetin CoFactor is the in-vitro activity of the von Willebrand factor which causes the agglutination of platelets in the presence of ristocetin. Decreased von Willebrand factor is associated with von Willebrand Disease, the quantitation of ristocetin cofactor activity is useful in the diagnosis and evaluation of this coagulopathy. It is also useful when monitoring patient response to therapy. Levels of ristocetin cofactor activity are determined by the ability of a test plasma and ristocetin to induce agglutination of a standardized platelet suspension. Results are determined using a lot specific Standard Reference Curve.
