Test Comments: Help
von Willebrand disease (VWD) is the most common inherited bleeding disorder with a prevalence as high as 1% in the general population; it is the result of quantitative or qualitative defects in the von Willebrand factor (VWF) protein. Affected individuals have severe bleeding that can be life-threatening if not recognized … View more
