Popis: von Willebrand disease (VWD) is a common coagulation disorder with a prevalence of 0.1% to 1.0% manifesting as a wide spectrum of bleeding symptoms. Type 1 is diagnosed by confirming a quantitative decrease in VWF level, while type 3 has undetectable levels of VWF. Type 2 VWD variants are characterized by functional and binding defects. Initial diagnosis and follow-up depend mainly on measuring VWF protein and VWF activity and calculating the activity to protein ratio. Ristocetin cofactor activity (VWF:RCo) is the most widely used and gold standard activity assay. In our institute, we use a cutoff of VWF:RCo/VWF:Ag
