The severity of symptoms can vary. Severe forms become apparent early on. Bleeding is the main symptom. It may be noticed if an infant is circumcised. Additional bleeding problems appear when the infant becomes mobile.
Bleeding can be caused by an injury. It can produce excessive bruising after a minor
or cut. It can also cause bleeding after extraction of teeth. Bleeding into joints is a common sign. This is called hemarthrosis. Intestinal bleeding may produce bloody stools. If it occurs in the small intestine it will cause black, tarry stools.
Mild cases may go unnoticed until later in life. Then they occur in response to surgery or trauma.

Coagulation studies look at the ability of the blood to clot. These studies involve many tests. They are done if the person tested is the first one in the family with the disorder. Once identified, other family members will need less testing for a diagnosis.
The doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
- Tests of bleeding time
- Blood tests to measure the amounts of clotting factors present
