Mild forms of von Willebrand disease can be difficult to diagnose because bleeding is common, and, for most people, doesn't indicate a disease. However, if your doctor suspects you have a bleeding disorder, he or she might refer you to a blood disorders specialist (hematologist).
To evaluate you for von Willebrand disease, your doctor will likely ask you detailed questions about your medical history and check for bruises or other signs of recent bleeding.
The results of these tests can fluctuate in the same person over time due to factors such as stress, exercise, infection, pregnancy and medications. So you might need to repeat some tests.
