Clinical validity: Help
This test diagnoses and subtypes von Willebrand disease (VWD) and pseudo- or platelet-type VWD. VWD occurs with bleeding symptoms at rate of 1 in 1,000 in the general population. In 10% of those cases the bleeding is severe. This prevalence makes VWD the most common congenital bleeding disorder known.
