Updates on Von Willebrand Disease Testing.
Clin Lab Med 2026 Jun; 46(2):153-165.

Abstract

von Willebrand Disease (VWD) is the most common heritable bleeding disorder worldwide and arises from quantitative or qualitative deficiencies of von Willebrand Factor (VWF). VWF is a multimeric protein essential for primary hemostasis and factor VIII stabilization. Diagnosis of VWD requires integration of bleeding history and laboratory testing. Traditional laboratory assays, such as ristocetin cofactor activity (VWF:RCo) are increasingly being replaced by newer methods with improved analytical performance, including VWF:GPIbM and VWF:GPIbR. Advances in multimer analysis, Collagen Binding, and genetic testing are further refining the approach to VWD subtype classification. This review summarizes recent diagnostic innovations.
