For people with a family history of hemophilia, it's possible to determine during pregnancy if the fetus is affected by hemophilia. However, the testing poses some risks to the fetus. Discuss the benefits and risks of testing with your doctor.
In children and adults, a blood test can show a clotting-factor deficiency. Hemophilia is diagnosed at an average age of 9 months and almost always by age 2. Sometimes, mild hemophilia isn't diagnosed until a person undergoes surgery and experiences excessive bleeding.
