A newborn boy was experiencing nosebleeds, blood in his urine, and easy bruising. Initial tests were normal except for slightly viscous blood. A doctor suspected von Willebrand disease (VWD) and tested for the von Willebrand factor (VWF). The VWF test was negative, indicating a defect in the VWF protein. VWD is caused by defects in the VWF protein, which is important for platelet binding and clotting. It affects up to 1% of the population and treatment involves drugs like desmopressin to stimulate VWF release.
