How Is von Willebrand Disease Diagnosed?

Early diagnosis of von Willebrand disease (VWD) is important to make sure that you're treated and can live a normal, active life.

Sometimes VWD is hard to diagnose. People who have type 1 or type 2 VWD may not have major bleeding problems. As a result, they may not be diagnosed until they have heavy bleeding after surgery or some other trauma.

On the other hand, type 3 VWD can cause major bleeding problems during infancy and childhood. As a result, children who have type 3 VWD usually are diagnosed during their first year of life.

To find out whether you have VWD, your doctor will review your medical history and the results from a physical exam and tests.
